I think so.

What's to stop Mark at Gox from front running huge amounts of cash that he sees is going to be coming in before it gets there?

This is a non-issue. In fact, several unrelated non-issues. First - the fact that somebody might find out where somebody else lives based on the ip address. This is not easy to do, even law enforcement needs a court order in most countries.
Second, the fact that somebody might find out where somebody else lives by gaining access to their personal computer and Web mail, with all the personal documents containing the address, etc. Note, this likely means access to their bank accounts and locally stored bitcoins (unless offline or paper wallets).
Third, the fact that somebody might find find out the identity of a person controlling a particular bitcoin address with lots of coins, and then find out the address of that individual from public or semi-public records. Note, this has got nothing to do with IP address.

Now compare this whole mix of unrelated or losely related issues with the fact that anyone wanting to steal something of value can simply (compared to the goatfuck above it is simple) steal a car, rob someone of their gold necklace, kidnap for ransom, or just break into a wealthy-looking home and hope for the best. Or start a bitcoin Ponzi scheme.

tl;dr - the OP is fear-mongering and spreading FUD. No offense, paulie.

If you are not going to keep an eye on the major developments in bitcoin during that time, then that would be your best bet for having a universally supported archive.  Extract your private keys.  Save them somewhere human readable (can you find ink and paper that won't degrade?  Maybe etch or engrave it into something durable?)

If you put it on a USB stick, there is a chance that in 10 years it will be difficult to find a computer that can still read a USB stick even if the wallet format is the same. How would you access a wallet that is stored on a 5.25" or 3.5' floppy disk right now?  What if you stored the wallet on a device that connected via Centronix DB-25 pin parallel port, or DE-9 serial port?  I still have programs for my old TRS-80 32k CoCo stored on audio cassette tape in my attic.  I have no idea how I'd ever get them off if I wanted to.

If you do not use paper wallets, really you are very foolish.

You back up your computer, of course. +1 for that.

But here's the thing, people can get to your computer. Its connected to the internet. There are already viruses that track network traffic, keylog, and yes deliberatly steal Bitcoin wallets.

Its already happened. Why should it not happen to you. So you are careful. Me too. Some of the people who have lost stuff in this way were careful too. Most not. It helps to be careful.

But the security of a carefully prepared paper wallet or many of them, is much more than a computer.  Having worked for an AV firm, we used to say that nothing beats physical locks. Its very true. A good hacker can get in most places given time and motivation.  

Anyone with any significant wallet should put it in paper wallets. Many of them. Thats my view.

Interesting idea.

I am not sure its very easy to find your actual address from an IP address, but given unfortunate circumstances, interception of email, etc it can certainly be done - after all you give your address each time you order something.

I think the thing that makes this unlikely is that the 'thugs' do not actually know where you store your bitcoins. If you are sensible, you will have moved most of them to paper wallets and so they may not even be 'at your address'.

Put a tool that will be able to extract the private keys out of the wallet.dat on the stick as well.
