Life on an island is not all it's pumped up to be. Takes PLENTY of work and maintenance (body, vehicle, home, land, etc.) whether you've got the buck$ or not.

If the rain don't come, where you get fresh water? A container on a barge from a cargo ship from.... someplace? When a hurricane or tidal wave rips through, what do you rebuild with?

Isolation on an island brings out 'interesting' revelations about yourself and others –– and the dynamics of living in 'community'.
The producers vs. the slackers soon becomes evident.
