As a human, your needs are simple[1]. With a $1M net worth, you can relocate somewhere to live very cheaply. And your dependents can live in that same place, also cheaply.
All you need to do is show the Joneses the door out of your mind and never let them back in, nor look toward their lives in envy.
[1]: Healthcare being a notable potential exception, depending on the individual.
To me this is the most critical problem with the "move somewhere crazy cheap" plan. I feel a parent owes their children at least somewhat similar opportunities as they themselves had. If you got to work as "high flying white collar tech worker", but the only option your children have is "subsistence fisherman", you have wronged them.
Even if your goal is financial independence, it's reasonable to not drastically decrease your existing standard of living just so you can retire _now_.
Whatever happens, perhaps AI replacing all cognitive work, you know you'll be fine. Maybe not able to live lavishly, but much better than needing to have a job you hate in order to survive.
You've hit the escape velocity. Worst case scenario (I'm simplifying) is that your NW stagnates, best case scenario is that your NW will continue to grow quickly. That's much better than the worst case scenario being that your unemployed with a zero NW.
