You’re arguing for something reasonable. The commenter I’m replying to quotes Dugin and alludes to something resembling a hermit kingdom. (Attachment to birthplace. Going into the local industry, skills be damned. Blood thicker than water and no “foreign” food.)
This is a recipe for nationalistic poverty. North Korea and Russia are going down this path. They’ll be poor and uninfluential. But if makes them happy, as long as they keep it within their borders, it is difficult to advocate for a shift from outside.
While I'm not sure which side of the argument I stand on, I do think it's pointing out that even if certain societies / countries do do the things, they unfortunately bare of the costs of others' decisions. A third of Pakistan being flooded is more likely a consequence of the West's energy usage and not due to their own doing. So it's a global effort to make these changes or limited benefits are seen.
You first.
Now, your turn.
These isolated communities exist. Their quality of life is lower. But anyone can join them. From hippie communes to Amish communities, Luddism has a long tradition in modern society. (I’m ignoring the ethno-racial undertone in implying there can be an objective arbiter of what counts as true local cuisine and culture.)
