I don't see it the way you do. What good will it do to have a privacy coin in the EU? Unless you want to buy stuff on the Deep Web, it's not going to do you any good. I will be able to buy it in a DEX, but I won't be able to spend it directly and if I want to sell it, everything will be problems. If I buy and sell a lot through DEX I will have a series of transactions to my bank account that I may be asked to justify and I will not be able to justify. Meeting in person has its dangers.
I don't see why I would want to buy a privacy coin then. To make it so private that I can't even spend it?
Not everyone "buys stuff" on the Deep Web. There are people who use privacy coins for legitimate purposes (like hiding their financial activity related to business, or simply to prevent third-parties from knowing all of their transaction history). Now why would transactions from a DEX be linked to your bank account? That would only happen if the exchange is KYC-compliant or centralized. The smart thing to do would be to buy privacy coins with cash (paper money) in person, and trade them against other cryptocurrencies on a decentralized exchange (DEX). No personally-identifiable info or trail would be left for the government to use against you. It's all about following the necessary security measures to avoid getting caught in the long run.
By the way, spending wouldn't be much of an issue since you can exchange popular privacy coins (like Monero and Zcash) for Bitcoin. You can then use that BTC to load a prepaid virtual card on MoonPay, or simply buy a gift card to spend your coins at your favorite store/retailer. Let's see what happens by 2027. I'm sure the EU will change its mind after increasing pressure from crypto industry players (mainly lobbyists).
