Earlier quoted context omitted.
In the UK that's not "that remote". There are 5x, 10x house price differentials for driving 3-4 hours up the road. Because no-one wants to live in a depressed town. You can live in a commuter town and not commute, sure, then you're not arbitraging CoL (it won't be much cheaper). If you live somewhere where there are no jobs then you have to deal with all of the issues I've stated.
Get out into the country proper, and you'll find plenty of rich people to hang out with. They don't tend to live in villages or towns, and they don't socialise with "townies", and they certainly won't share any interests with some nouveau-rich tech worker who thinks they're wealthy
You seem to have this idea that everyone here thinks they're uber wealthy or whatever. It's just relative to the locale. If you move to a depressed northern town with the idea that it's going to be some utopian bliss in your massive house then you are in for a shock. That's what is being discussed.
Obviously there are nice places outside of metro areas. They have a price tag to match, or not, the land isn't for sale.
You're also illustrating the other side of it - it's not easy to slot into a different social class (upwards or downwards).
