The vast majority of people here on Nostr get this. The vast majority of the world does not get this. It's why Bitcoin and Nostr have such small amounts of adoption. ZBD is an on ramp, IMO. Just like Coinbase, etc. Eventually you understand this and leave Coinbase with your funds. Coinbase still knows about all of those purchases though. Just like leaving ZBD, they could still have your NSEC. You won't truly be free from either until you go no-KYC and self custody. But you could generate a new NSEC yourself on a new client, just like buying no-KYC from Bisq. It's the same to me.
