He is sadly right. This is mostly toxic and idiotic, but some good people who genuinely want the best for our kind.
OP:
Important that its also in a colder climate, like it or not climate change is real.
Colder climates will become less so, and that will mitigate climate impact and desertification.
With the added bonus that only really whites and asians endure in cold weathers, or even seek them out.
Important to be connected to the real world outside, there is no need to be hyperisolationist.
IT skills can bring money to the community, community made IT software can enrich all.
With this can come investment in technology, a chemical reactor would likely be important, being able to either buy or make your own medicine is crucial.
3d printers are important, there is a reason humans developed technology, it might sound romantic but spending several days of very hard work to make a damn chair is not fun, and will not allure to a lot of people.
Some hardship is needed to keep people hard, but not to the point of devolving to the iron age.
Renewable investment so energywise there is independence, even perhaps sale back to make money. Sustainability is crucial, you want to lead by example, sooner or later you will be found by the world at large, and you do not want to look primitive, you want to look like something that others would follow, would respect. Because it will be damn hard to respect an "ethnostate" unless its highly successful and people are proud of it.
To maintain morals and code of conduct, do NOT censor anything, do not restrict internet access, do not sabotage curiosity out of fear, this is how revolt and rebelion starts. Instead, show the horrors of the degeneracy, show proof of what you stand for to your children, the WHY, not just "because its bad". There is no respect in that.
This is why the modern world has become worse parents arent parents, they have no patience or time, they do not lead, they demand obedience.
