I am curious what you mean. Wilderness tends to be quite affordable, a couple months’ cost of living in a western country. If you want you can get a mortgage for something else and use that to buy wilderness in a country with no extradition treaty. Hell, there are places on Earth you can just be and no-one will find you to tell you you don’t own it.

But you haven’t done that, so presumably you want some level of survivability, social protection, social services, and perhaps even social interaction. So what is it that draws you to the dream? What do you want, and is something like that more feasible?

Could you be happy subsistence farming? Living in a commune? Living in a town but within biking distance of a nature reserve? Living off donations in a society that has mendicant monks? All of these are already possible.

Or do you want post-scarcity communism that still gives you stuff even if you don’t help others and live remotely because it’s post-scarcity?

Because even if we have a good communism, we’ll have to see how much we can make post-scarcity while the consequences of capitalism are coming due. If there are a billion people migrating away from deadly wet bulb temperatures and failing crops, people may be too busy helping them find a place to help someone who won’t help others.
