I get that it goes against the fundamentals of crypto currency, but exactly for what reasons though? Assuming you're not using it for anything illegal (if you are then it's understandable), why the concern? I'm asking specifically when trading.
Because privacy is a right and not some sort of luxury that should be almost impossible to get and people have different standards when it comes to this, so the argument that many people use of having nothing to hide does not apply at all, for example with fiat if you want to exchange a 100 dollar bill for another currency or even you just want to get some bills of a smaller denomination you can do it without having to identify yourself, but somehow governments want to force us to go through KYC just because we want to exchange our bitcoin for some ethereum and that simply is not right no matter how we look at it.
