The government wants to be in control of the money and they also want to stop anything that might undermine their own currency. They want the ability to tax and seize at will. Crypto makes this difficult which is why I see them trying to stop it in the future.
Tax is a good thing and evading it means that you are not bringing back something into the community, it is natural that the government is going to hunt down money launderers because those taxes could be used to build projects that will benefit the many, I understand if some launder because the government is corrupt but with you evading taxes, you should at the least bring something back in the community.
