if you don't want to involve title deeds changing hands (or legal documentation indicating ownership changes), you risk forfeiting protection of the law.
That's the goal of crypto, isn't it ? To forfeit "protection of the law" so that in the end, we can do away with law and state.
Anything else one does with crypto, begs the question.
I don't know if that was Satoshi's goal or not since I haven't actually read the original white paper. For me it's sufficient to do be rid of perpetual inflation. I'd also lilke to see income and capital gains taxes eliminated and if crypto ends up giving people a weapon to fight against this kind of demoralizing taxation then that's a good thing.
