i'm not taking issue with the gist of what you've put forward.

neither am i suggesting that any particular law is just.

you asked a question regarding a topic that's discussed pretty extensively in political science/ political philosophy, i'm only bringing what limited expertise i have in that realm to bear on the conversation.

put another way, power is the ability to force/coerce. authority is the socially recognized ability to dictate.

when it comes down to it, they can't have my keys... nor do i think they have the computational abilities to find them. therefore, they don't have the power to take my bitcoin. they do however have the authority and (more fundamentally) the power to violate my liberties if i refuse to "comply" with their bullshit. that makes me want to get into the countryside asap.
