Only thing is, John Doe won't ever understand why *he* should buy a BFL Single or similar in order to protect the network.
It's truly sad how little some think of their fellow man.
The governments of the world are doing a great job of dividing and conquering humanity.
Your confidence in your fellow humans is inspiring, but let's be serious. But western standards of mathematical literacy are pretty bad, and certainly well below the requirements of cryptography. I didn't mean to insinuate that other people are stupid, rather that the concepts behind bitcoin are not at all simple and, more importantly, completely change our understanding of "money", and that the banks and the police and the government's finance department won't be able to fix our money problems anymore. I think most people won't be able, or have the necessary time to dedicate, to understand it. And that's why ASICs will centralize power in the bitcoin world. Bitcoindom is surely dominated by geeks, for want of a better word.
But it reminds me of a joke: "just think how stupid the average person is.... yeah, half of 'em are stupider!" You might or might not find that funny, but most people on this forum should be able to tell why it's actually
wrong (mathematically speaking).
