Original parent comment was talking about making 95% of bitcoin uses illegal. There's nothing inherently illegal about I.O.U.s, script, payment-in-king, etc. as you listed. Making tax evasion with bitcoin illegal is very different from making 95% of its uses illegal.

Personally, I'm fine with the government taking a cut of my bitcoin profits. It's profit, fair enough. I'm happy with being able to store wealth in a method that can't be seized by the government (whether that is by simply printing ridiculous amounts of money, or otherwise), and being able to send money anywhere with basically no charge.

I was going to buy a PS3, but why should I support a company that discourages me from using my hardware how I want?

The open pandora system looks like a much better place to spend my money. An open source handheld gaming system, yes, it can work: http://openpandora.org/
