Really doubt we will ever get to that point. Even if it does, people will learn some very expensive lessons. Seems many have already forgotten about mt gox, FTX, blockfi, Celsius, etc.

I think many of us actively encourage self custody and help move people away from custodial solutions but this is not going to happen overnight

Nostr helps. Knowledgeable bitcoiners having their own kids who will end up inheriting self custody coins also helps.

Bitcoiners are hypocrites (myself included) and have an extremely high time preference.
