Can you please elaborate on why something needs a URL (domain name) if a paywall is needed? The simplest nostr-native way to have a content paywall is 'zap this note, get DM with content'. No URLs. The simplest nostr-native way to have a paid service - 'zap this note, get 1 month of our service for the zapping pubkey'. No URLs. I think we habitually assume that nostr needs to integrate to the web, that web is more fundamental. That is kind of true for now. But I've come to think that if we succeed, things will flip, and web will become just one of presentation layers for nostr. And nostr pubkeys will be much more important than domain names.
