I find it really hard to understand, but I think the thing I'm missing is that the person who buys Taler in the first place simply has to trust the issuer - because they can't verify that they've actually received any without leaving a record i.e. becoming a merchant who is receiving Taler in exchange for cash.
So if you get Taler from your bank and spend it somewhere, the government can see it at your bank, and they can see it where it was spent, but they don't see you at all. You've done your trusting out of band.
If that's right, it could still be used for illegal and untaxed transactions if the entire chain was trusting out of band. I could use it to buy drugs without paying taxes if by dealer would be happy to shoot me later if they couldn't spend it at a retailer, rather than to check if it was good.
I still don't understand it. I've tried periodically for years, but I'm missing something.

it's more transaction tokenization system then a crypto currency, so you don't really "buy Taler (currency)", you give Taler digital Euros and they give you a token representing this digital Euros in a more anonymous way. (They also can work for other currencies, but doesn't do currency exchanges/cross currency transactions itself).
Effectively this means:
- The merchant (e.g. your local grocery store, restaurant etc.) doesn't get information about you they can aggregate, sell etc. This is the main improvement.
- It's not controlled by a US company, this is also a pretty big improvement.
- Taler doesn't strictly require customer wallets to be bound to an bank account nor do they identify who you are as a customer. This makes it hard for Taler to abuse the audit log, which is also an improvement.
- It does strictly require merchants (anyone receiving money) to be bound to a bank account for given currency (here Euro). It's best to think about it as the money going directly to the merchants normal bank account.
- Taler has audit logs containing what token was used from which customer(id) with which merchant (which is strictly bound to having to have a bank account), as well as logs about how money got into the customers wallet and all this methods you can put money into it will (likely) be traceable, so criminal investigator and similar can still pretty much trace back who did which transaction when. Just with a bit more effort/extra steps. So with enough automation states can as much surveil you then they can now. Practically it seems to make things a bit more high effort then today, which is a good thing to have.
IFF Taler allow putting digital Euros into a wallet using gift cards buyable with cash this indeed could still be used for money laundering (similar to how most gift card systems can be used for it), but I think it's unlikely they allow such things and most people practically will likely link up their bank account.
Another thing to consider is that for any ordering of physical good you normally have to put in a shipping address with your name, even if you send it to a post box.
And for a bunch of other things the vendor also has to get your identity out of band (independent of used payment processing). E.g. many kinds of contracts, high value payments, currency exchanges etc. etc.
This doesn't make it useless. It still is an improvement. Especially if payment terminals in physical shops get support for it and/or digital goods can be bought with it. In Germany a lot of the large chains with physical shops more or less all use the same payment terminals for card payment with support relative flexible software so it's actually possible I think. Just hard to happen without regulatory pressure, similar to Wero support on a payment terminal.
