Yeah, but even more fundamentally you also dont know if the private key that is at the basis of the multisig exists somewhere. Transfer of ownership requires a record one way or another, and so we are back to all the ledger shannigans we are all too familiar with. I agree ICANN can't be beaten when it comes to this stuff; this means the problem has no 'solution', mere mitigation with trade-offs one way or another.
Hence i am so bored and tired of thinking about this, and just grugbrain myself behind Nostr; because ultimately what we need is 'sort of good enough'+momentum=succes. I believe Nostr is sort of good enough and has momentum.
Congratulations on building the Nostr's Ethereum
