Well EU plans to start
blocking anonymous wallet transaction which they could literally make it a hunt for criminals not just for launderer that they usually say.
And then this CBDC although it will take a long time before they could come up perfectly, stablecoins might also be screened or banned because they think that stablecoins are going to be widely used than the CBDC.
That sort of make sense when you consider the past. I mean making anonymous wallet transactions would be basically a way to hide your money from government and government only allows people who bribe them to do that, if you are not some shady bank bribing politicians at all times to keep quite about the things you do, then you will not be able to do anything illegal.
Look at the mafia world, do you really think that they are not known or can't be caught? I mean the governments of the world could end the mafia world in a day, and I mean ALL mafia all around the world, all cartels all drug lords, all mafioso everyone you can think of will be jailed within a day, millions of people all around the world, why are they not doing it? Because they are bribed that is why. So, if you want to do anything that is against the law, just bribe the lawmakers.
