... not part of an cabel ... but ... i think of buying / selling goods on a nostr based platform. it's gotta have something that gives it an edge of existing trust accepting platforms. 

... just from a #UX pov ... if it feels sketchy and non-recoverable, its hard to get ppl to come back after a fail. Building trust in user profiles is sort of a base layer... sure it happens over time. but there needs something to be there early on to help get those first 1000 users.
