There is "Programmers village" ("Поселок программистов") in Kirov Oblast in deep Russia.

It is not exactly a rural community: it's just 20 or so families of remote tech workers (mostly freelancers) living a few kilometers from a small old town with dirt cheap land and local labor (like "buy a two-story house with one month's SF salary" kind of cheap). It was founded before the pandemic by a guy who used to work as an SWE at Yandex and grew tired of living in Moscow.

I wonder if something like this exists elsewhere.
