I would probably invest in undeveloped land, in several parts of the globe, plant a large permaculture fruit forest in each place, and maybe build a low maintenance primitive building/fort in the center of each plot.

Then I would party and behave like an animal, and probably spend or loose what ever I had left... Escape to one of the fruit-forests and live off the land like a savage beast forever...

Or something... 😆

Interesting question by the way...
