One thing worth mentioning, the complexity of a stateless system is just so much lower than a stateful one, that it makes sense from an engineering perspective to consider if state is really necessary or if it's just an excuse to track users :P
But of course, sometimes you definitely need state/accounts/users , in which case PROXNUT may not help much
Thanks for the feedback!
I know a few companies in the space looking for something that I've described above so I appreciate your thoughts there. I do like method 3 as well and like that ecash API tokens would still be useful even if it is not being used for a forward-looking privacy preserving method, for state requirement reasons.
