OK, but it is actually possible to be extremely private with bitcoin if you want to.
If you use things like bitcoin mixers, or pay/sell bitcoin for cash, it can be extremely difficult for people to track you in a mass collection scenario.
People get away with buying drugs on the internet, or blackmailing people with ransomware all the time and most of them don't get caught.
Sure, if the government is sending black vans to your house to spy on everything you do, you are probably screwed no matter what you do.
But most situations aren't like that. And bitcoin fits the bill for being pretty darn anonymous if you actually go about it right.
