Has anyone seen/heard of a project that anonymizes/privatizes purchases of "vice" products (beer/wine/marijuana/contraceptives/etc)? It seems like an obvious place where nostr/lightning could work. There is no reason why the random person working behind a counter needs to know that I purchased a bottle of wine, just that I'm old enough.

I know I have heard some discussion of this, but I can't find anything.
