... with the currently known physics.

When dealing with people like cunicula, be sure to set it to high-range mode to avoid overloads.

I assume that would hide your tracks.

Many merchants start out converting everything to USD (or other local currency), but then after some period of time start increasing the percentage they keep in BTC.

Because those of us not doing anything illegal and not being overly paranoid(*) think that using TOR is inconvenient and slow.  

(*) And that may be a significant fraction of all bitcointers.

You don't need to have a website behind Tor in order to use Tor to access it and protect yourself as far as I understand it..

Maybe the OPs question should have been

"What can the state do?"

it would make for good starting point for an analyses of possible state/supra-state attack possibilities upon bitcoin.

The government claims inflation is 9.9% and has outlawed calculating or quoting any other inflation rate. Forty percent of dollar deposits have been withdrawn from Argentina since last October. Now there are capital controls. You need special permission to move your dollars overseas.

To take a foreign vacation, Argentines have to apply to a bureaucrat for permission and explain where they got the money for the trip. And there are rumors that it will be made illegal to talk about the existence of the shadow market exchange rate for dollars.

If you pay in dollars, you could get 25% off the price of property. The government has outlawed this, making the buying and selling of real estate in dollars illegal. Just one more rule Argentines will find their way around.

The government claims that the rate of outflow has slowed. But with every passing week, companies and individuals figure out new ways to get their cash out.

But they continue to do incredibly dumb things. Two years ago, President Kirchner seized private pension accounts. Now she is going to lend $4.4 billion of this money, at a rate of one-tenth the inflation rate, to new home buyers. A lottery will decide who gets the loans – not capacity to repay.

umm, simple approx. says about 6 days, 16.6 hours from nowish ... so 2100 28.11.12 UTC ... roughly speaking?

Well, this is true.  Unfortunately, the per capita percentage of underground economy in the U.S. is nowhere near the levels of countries like Argentina or Ecuador.

The credibility of the current politicians might be low, but the credibility of the state as a religious idea, is at an all time high.

Cloudflare is a US entity, and as such subject to the US PATRIOT act. Making the Web insecure pushes more people towards cloudflare, which in turn provides more opportunities for massive data surveilance by the US government. Imagine the reaction if Chinese government was trying to route as much traffic as possible through Chinese-operated infrastructure...

The second biggest risk is that the government declares bitcoin illegal in some way (probably saying it supports terrorism or some other kind of nonsense). Scoff all you want, but making it illegal in some fashion will scare away all of  the people you are counting on to buy your million dollar bitcoins.

The biggest risk to bitcoin is that the government will try to regulate it. Again, it doesn't matter if it is possible, or successful, or not. The result of regulation will be that most people will avoid bitcoin because it won't be worth the hassle, and your dream of million dollar bitcoins will disappear.

Today, Argentina is back in a bind. There is a strong possibility of another crack-up within the next year. And then we'll have the same opportunity we had a decade ago. 
 
The signs are all there. The streets of Buenos Aires have recently seen the return of the backstreet currency exchange.
 
According to the official exchange rate, which is subject to capital controls, 4.4 pesos buys you a dollar. But on the street, people are happy to pay up to 6.7. Inflation runs at 25%. The purchasing power of an Argentine's peso savings is going down by one-quarter each year.
 
The government claims inflation is 9.9% and has outlawed calculating or quoting any other inflation rate. Forty percent of dollar deposits have been withdrawn from Argentina since last October. Now there are capital controls. You need special permission to move your dollars overseas.
 
To take a foreign vacation, Argentines have to apply to a bureaucrat for permission and explain where they got the money for the trip. And there are rumours that it will be made illegal to talk about the existence of the shadow market exchange rate for dollars.
 
But a lot of Argentines' dollars and pesos don't reside in bank accounts. Property transactions typically take place in special rooms in lawyers' offices, and they're cash deals. There's that much distrust of banks. They are fine for day-to-day things like paying your electric bill. Not for your savings, though.
 
And these transactions more often than not take place in dollars... If you pay in dollars, you could get 25% off the price of property. The government has outlawed this, making the buying and selling of real estate in dollars illegal. Just one more rule Argentines will find their way around.
 
By some reports, if an Argentine company complied with all the taxes and tariffs it faces, they would eat up more than the company's pretax profits. So the shadow economy thrives... by necessity, it seems, rather than greed to pay less tax. Middle-class day-trippers take the ferry to Uruguay to put their savings in deposit boxes. The rich spend millions on condos in Punta del Este, Uruguay.
 
For Argentines, real estate is their bank. They understand inflation and expropriation from bank and pension accounts. If they have some spare cash, they'll buy an apartment. Or a beach home across the Río de la Plata in Uruguay. Or a condo in Miami.
 
Now, fewer Argentines are using local real estate as a hedge against inflation. New construction and permit applications have fallen off a cliff. They just want their cash out.
 
The government claims that the rate of outflow has slowed. But with every passing week, companies and individuals figure out new ways to get their cash out. For instance, companies buy financial instruments locally in pesos that they immediately resell in New York for dollars.
 
Argentines have seen it all before. When a government and a banking system take your life's work with the stroke of a pen, you don't forget. If you're lucky enough to rebuild your savings, the next time you will be ready. And the harder the Argentine president, Cristina Kirchner, tries to keep assets in the country, the more they'll be siphoned out.

We should encourage our representatives to write laws

I don't think we have the critical mass of bitcoin users needed for it to be much more than a gimmick to draw in new customers at this point.

'

I am working on system for people like you, You would be considered a independent sales agent for Bitcoins-R-us. This will work like this,
we have a base price called a discount we charge our independent sales agents we will say .5%. The agent then signs up a merchant and he adds his discount to the base discount and it comes to 1.5%. So now the agent makes 1% of all that merchants transactions.

This is just a rough outline of it, we are still fine tuning the actual discounts and things like that.

I am not anti-union, but I am suspicious over any monopoly.
