I do not see the attraction. How much is maintenance on a plane? Fuel? Landing fees? Also, when you need to go buy some groceries, where is the nearest store? IF you feel like a drink or dinner, where is the nearest nice restaurant or bar? Can you get a UberAir home? How do your friends pop round to visit? Do your kids get homeschooled?

If you fly to San Diego I guess you will land at Montgomery Field, which is miles from the beaches or anything. In fact, does it cost money to store a car at Montgomery Field?

It honestly sounds like some prepper fantasy. Most people want to stay closer to civilization. Humans are nothing by themselves.
