That doesn't acknowledge how fundamental relays are to nostr. It's in the name! VPNs are not some fundamental element of MacOS or Linux.
Without relays absolutely front and center, you have to ask: Why Nostr? If relays are just a credible exit then choose another protocol that is way faster, and way more consistent, and that also offers a credible exit?
What's the answer? For users for whom relays are some shadowy thing that they may or may not ever discover, why Nostr?
