You're more optimistic than I am for sure. Most normies will just do whatever is default, and being a sovereign Bitcoiner is most definitely not the lowest-friction, default path.
At this point, we'd need institutions to fail (e.g. some large ETF or exchange to get hacked, or get caught selling Bitcoins they don't have) or a Great Taking type scenario to get a self-custody revolt.
It's best to just focus on oneself, e.g. start your own, small community, be self-sufficient, enjoy life.
