Well, your write-up here is quite interesting to read, but I don't believe that is going to happen. Yes, the government will create their own central bank digital currencies, but they are not going to be getting rid of cash.
It makes no sense that governments and central banks make their own centralized coins if they want to keep cash, and we have examples of Sweden and China who are already testing this big time and they are almost not using anymore cash even today.
When it comes to DEX/P2P, you can send and accept whatever you want and still maintain your identity, so this does not affect these platforms. If the government can stop anything that has to do with crypto, they can't do more than they are doing now; banning centralized exchanges, because they only have controls over those.
They are eliminating P2P exchange with physical cash so you have one option less, and using their digital wallets will be much worse than using bank accounts today.
If I want to exchange my Bitcoin for cash I can do it today and there will be no trace how I spend my cash.
And lastly, they won't stop cash, we are still going to have the current monetary system. That's all I can say for now.
Wake up and read their official documents with full plans to make this a reality and don't just speak from your head.
If they have plans to go cashless with full tracking and people say nothing and don't complain then it will happen sooner than you expect it.
