Here's a few options I have...
Save as much as possible and take it all to much cheaper countries. Vietnam, Indonesia, etc you can live for years on the savings from a year or so of work.
Buy cheap land and homestead
Monastery or communal living
Volunteer with WWOOF or workaway long term
Work seasonally take the rest off. Firewatch, ski bum, etc
FIRE as mentioned in another comment. Takes a longer time but if you are super frugal and have a high salary actually very doable in 5-10 years. I suggest looking at mr money moustache.
Also dropping out. Look up how to drop out there's an old famous article about it.
Overall read Early retirement extreme it gives lots of good ideas too.
After looving at various possibilities for a few years I am much more hopeful cause I realized there are tons of realistic options!
