Maybe this is the right way of doing it: A marketplace of relays.
Integration with a market of relays, similar to the nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 except for digital services and in this case specifically for nostr relays, I think would help here.
The "defaults" would be based upon a social graph and nostr listed relays on the market, also on nostr.

I think so, could also apply to VPNs, image, audio and video hosting and distribution and far more.
