I will not commit to any sort of absolute rule of “which societies are protected from forced economic and social manipulation.”
Partly, this is because I believe economic coercion is real (contrary to certain ideologies), but also because all communities are always at risk for “forced economic and social manipulation,” and the world of communities is more like an ecosystem than not.
Things like property rights and national boundaries always exist within the context of force.
Still, I tend to take a more Utilitarian than Deontological view. The fact of the matter is that some people really like living the Amish life.
So I am willing to outline some rough things.
1. Do I have to pay for the community’s externalities, directly or indirectly?
With the Amish or Japan, largely no. With the Middle East, based on future migratory conditions, yes, and with resource conditions, nations that have a very high fertility, also yes.
This includes the dominant political conditions within my nation. If my nation’s dominant political figures are always demanding refugee intake, or mass migration, then practices I could potentially ignore before suddenly become my problem.
2. How well-functioning is the community internally? Do people actually like it, or are they just prohibiting anyone from escaping?
In many Islamic countries, being an atheist is very dangerous, and attempting to leave Islam risks death, this is in addition to things that aren’t even mandated by Islam, such as the burkas or FGM. The GDP is low, the corruption is high, and the economy only hangs on because of oil revenue. Debilitating preventable medical defects pile up due to generations of cousin marriage. (Also, Islam demands to spread.)
So it isn’t functioning well, and it uses some pretty extreme measures against half the population, that other traditionalist societies don’t.
By comparison, the Amish don’t appear to have this level of internal dysfunction, and they have some preventable genetic issues, but it’s because of a small founder population. They specifically send Amish people out into broader society to see if they want to stay Amish, and I’ve never heard of anyone getting killed for leaving the Amish life.
3. Just how many resources are they tying up? Can we afford it?
As mentioned earlier, the marginal cost of just leaving the Amish where they are is not that high. It could be too high if that land ends up needed in order to win a total war, but that’s unlikely.
If too much land is Amish, that makes the country unable to be adequately defended, and like with gold miners killing an uncontacted tribe, eventually someone else will enact “forced economic and social manipulation” on them instead.
In the case of Japan, they’re at parity with the global economy, producing value and all that.
4. What is gained by leaving them there?
There are benefits to having a small population of Amish. The first is that they produce various craft goods that people like. Also some people like to live that way (and if they’re small enough, the rest of us can act as a defensive buffer).
But also, it’s important to have some knowledge of by-hand manufacturing and farming practices in the event of some kind of technological catastrophe. Normally we’d have to pay people to do that, but the Amish do it for free! (Relatively speaking, based on existing property laws, and with an opportunity cost in technological output.)
I don’t know with certainty what all the disasters and problems having Amish hedges against, but my intuition is that having some functional low-tech groups around lowers humanity’s existential risks by a good chunk. Though I’d ideally like them on some island or other area that would be more difficult to raid if the cities fell due to technological collapse.
So, when we take all that together, I end up being more of a Nationalist, and at odds with the Progressive Leftists and various other groups. (Thus, for instance, suggesting giving the White Nationalists land for making some tiny city-state somewhere to shut them up and as an experiment, etc.)
