Don't forget that the 10% with BTC will be the ones with enough money to give anonymous perks to the politicians that run this place.
With true anonymity (Bitcoin doesn't and can't have it, see below), then the politicians can hide their ill-gotten wealth too. So then they will not be afraid to rob the government blind, and government will collapse rapidly.
That is the perfect outcome, because I've shown mathematically that all prosperity is due to technological innovation (i.e. productivity increases) and small government getting out of the way.
Or whoever receives it sends it through a bitcoin mixer or CoinJoin, and the coins they end up with are no longer linked to be, and are spread among a dozen or more other random unknown people.
It's a good thing bitcoin has it then. You just have to work a little to get it.
I am going to school you again.
I have explained numerous times that mixers are basically useless if 99% of the users are not doing what is necessary to be anonymous, because then your new coins can be discovered with probabilities and a process of elimination.
Bitcoin does NOT have mandatory anonymity and thus it doesn't have anonymity at all.
Anonymity is an significant-minority-or-nothing proposition.
And if all of the significant-minority are tainted coins, then the authorities can just blacklist all the 1% or 10% that come out the other side of the mixer by the process of elimination.
For anonymity to work, the users in large part have to all be anonymous.
P.S. I've introduced ideas for physical Bitcoins in order to obtain more widespread anonymity.
