I don't get your point. The current proposal for a digital euro supports private peer-to-peer transactions

private and anonymous, especially from the government are two totally separate things.

If I am understanding Taler, it is not like cash coins/paper where the government does not and has no way to know that you, e.g., bought a bottle of wine from a vintner with cash, and that vintner can use that bill/coins in many different ways and the gov't has essentially no way to trace or track that.

The way I am seeing it... please correct me where I'm not understanding something... the Taler architecture would require you to pay cash into an exchange, then you extract (likely IDs/tagged/marked) Taler, you then pay that Taler to a merchant, e.g., who by policy cannot remain anonymous, and that merchant deposits that market Taler into the exchange. So in that scenario, what has happened is that the Taler the merchant received "privately" is clearly associated with the Taler you extracted from the exchange to pay the Taler deposited by the Vintner.

It's maybe private in that the Vintner does not need to know who you are, but you can bet the control freak tyrants in the government will know that you bought that wine.

So what you may say, wine is fine, but what if it's something the government doesn't want you doing, buying, supporting? Maybe wine is now illegal because {fill in the reason}, maybe you are not sufficiently obedient and compliant during an "emergency" and need to be cut off? Maybe you are sanctioned by the EU and all your money is taken and you have no means of even feeding yourself other than the "humanitarian" limit of living on €200/month and you can't even return to your native Switzerland from Brussels because you are not allowed on trains, planes, or allowed to drive across borders like happened to Jaques Baud for speech some tyrannical EU politician or bureaucrat did not like?
