There was a time when bank card number was practically all you needed to get someone’s money.
I think Estonia’s electronic IDs are the best, they have the government sign (sometimes provide, but generally just sign) your public key. It’s both that the government doesn’t have your private key and that it’s immediately usable for many things. I don’t know if they do, but one can also make ID cards (with a necessary chip inside, of course), where a private key can be written and used for signing operations, but not read back.
Modern technology allows so much goodness that politicians and corps have just started globally gaslighting us over what can be done and what can’t. Stalling on technically easily solvable issues, so that it wouldn’t come to real ones.
The simple act of comparing signatures meant that it was very difficult to randomly target people. We don’t have anything like that today, like a key/token pair.
