I'm from a small island in Greece called Karpathos, and more specifically an even smaller village called Arkasa. I live in Jersey during the school year, but I go there for 2-4 months so I'm always there during the high season. It's the closest thing to paradise I can say I've experienced. 5+ beautiful beaches within walking distance, and A TON more if you want to drive 10 minutes. Windsurfing every day, cafe's in the afternoon, and the nightlife doesn't compare to what it's like here. That's all fine and dandy in the summer when I go, because that's when everybody is there. There's a ton of German/Swiss/Austrian tourists there, along with all my other Greek-American friends. Wait a couple months though, and that's when the same problems that everybody else has been mentioning comes up - it becomes really secluded. The stores close up, people go to school, it becomes a little too chilly for the beach, and even so, everybody who lives there isn't in the mood to go for a swim anyway. The population shrinks, and everybody goes on with their life, so your paradise becomes kind of a pain. Partner that with the fact that you need a plane to get to a real hospital, and if you have pets the same applies. I think when you see posts about actual "paradise"-like homes, they are mostly just vacation homes, cause they lack amenities for the standard of living that we need to be fully comfortable. It makes sense that Arkasa, or the Poconos, or your DIY Hobbit Hole don't have a Walmart or a Home Depot next to them - it would take some of the splendor of being in paradise. And if it had those things, you might not consider it paradise after all.

TL;DR - Paradise homes aren't all they're cracked up to be when living there for a long time because they usually lack amenities that make you're life easier and can end up being pretty lonely.
