Can someone please explain this one to me?

I’m a bit dense and don’t get it.

I think the idea is that their life on this island is more enjoyable than their previous life. So they decide they want to stay there after all.

Which honestly is understandable on an emotional level sometimes but realistically they would be dead after a few weeks from unclean water, wildlife, infection, illness, etc

Yeah, I get wanting to unplug and get away, but the first serious illness or injury will have them wishing they still had a way to call for help.
Even beyond that, I think this sentiment is easy to get into from the comfort of climate controlled, weatherproof structures, with abundant food that doesn’t require months of forethought and planning to farm or energy expenditure to hunt or gather. I’d love to chuck up materialism and peer pressure, but I’m firmly attached to the various infrastructures that make my life so comfortable.
I think the flush toilet is the unsung hero of modern civilization.
When my mom had to poop as a kid, she had to stand on two planks of wood and squat over a hole in the ground, out in the open. I love my toilet.

A hole dug in the ground and filled in after use

Natures flushing toilet

Well that’s nature’s toilet, not nature’s FLUSH toilet. Its also far from modern civilization. It works okay for one or two people in an area they don’t live in. It doesn’t work so well for massive populations on top of one another. I’d even argue that without flush toilets we wouldn’t have modern civilization.
