But it seems you are totally missing the point of Taler, as it doesn’t even aim to be anything like so called crypto-“currencies”. It’s a digital payment system like Paypal, but decentralized.

No, I'm not missing that point, I understand the design goals of Taler. You seem to have misinterpreted my comment. I am pointing out that the inability to store Taler currency in a cold wallet is counter to existing user education from similar systems (digital currencies) and therefore will lead to loss of funds of users who don't understand how Taler works.
