Alas (in my opinion), eventually absolutely everyone (whether someone wants to or not) - but will have to pay taxes + prove for the origin of earnings. Far from the fact that this alternative will be, I have very big doubts about it.
Therefore, the delisting of such (anonymous) coins is the first sign that this is just the beginning. It will be mandatory for exchanges to get rid of trading pairs. Because the SEC will shut them down. It's business as usual. 
I agree with what you say, but I also think that things could even go a little further. For example, blocking all cryptocurrencies whose origin cannot be verified or a higher percentage when taxes are declared on them, or even that the law has the ability to confiscate said cryptocurrencies when the possible origin derives from a crime.
Eliminating privacy coins is the first step towards more complete control of citizens, regardless of country or government, which has always been the goal. In this, CBDCs play a very important role, since being digital, governments will know at all times how much money we have and how we use it, so our privacy will go one step lower. Although it may not seem like it, both things have a lot in common.
