I'm a State actor. I can hire detectives that will go through the blockchain and monitor your traffic, and I'll likely get a fair approximation of how many bitcoins you have. Or you can just tell me when asked, as a good law-obeying citizen should do.

This is how all tax works, btw. Income tax is nothing but a wealth tax limited to wealth accumulated over a certain period. There is nothing impossible about it.

What traffic? They're stored on my hard drive. I don't fire up the client. I don't buy things with them. I just sit on them.

[toyg]

Ok, I'll make it easy then and just sequester your hard drive. Oh, it's encrypted and you won't give me the key? I'll throw you in jail.

[iopq]

How do you know to target me?

[toyg]

Yeah man, ninjas don't pay taxes, sure. Have fun.

[iopq]

No, rich people won't pay this tax. Because they have that much to lose.
