Re: 1., I’m personally unwilling to move outside the U.S. but agree it could make sense if you can make it work for you while maintaining a high salary.
Re: 2 and 3, I completely agree. I think in particular about longevity medicine as a potential future expense. You can certainly build up support for higher-than-current expense levels to address these risks. You might also retire to less profitable or more risky activities that you find more enjoyable (but that supply >0 income), or simply stay in your current profession—but with the advantage of having higher option value.
