I’m all for bitcoin but your examples are essentially I want to do all these generally illegal things that I cannot within the current legal framework.

Some of them are, when the country you're in is oppressive. But having something that can do that is good.

And many of them aren't things that are illegal, they're false positives or limitations that the existing system doesn't care about because they affect minorities or disenfranchised people instead of anyone with significant political power. It's not illegal to have the same name as someone on a list. In the US it's not illegal to buy many things but people are still deterred from doing it if they know it won't be private. Prohibiting donations to Wikileaks was never claimed as an official government requirement -- probably because it would've been unconstitutional -- but the major payment networks still did it. Transferring money to someone in South America isn't inherently illegal, the existing system just makes it a pain through normal channels.

It does the things the existing system doesn't. Which isn't always because they're illegal. Sometimes it's just because the existing system sucks and doesn't care about you.
