Nostr certainly could.

Should we? The major delivery platforms have lost money hand over fist since their inception. 

A Nostr app wouldn't need the lobbying, the DEI or the marketing budget. But combating organised fraud of customers would be a nightmare, I think. 

 Thats sort of what I was thinking. I would rather get in a strangers car that is kinda sorta the responsibility of a company. It would be so easy to kidnap people and extort them without a trust system thats reliable. Reliable real time updates are needed too.
