I find it hard to read your argument and not feel that the nations and individuals who follow your advice will be replaced by those who don't. I suppose this is "wrongthink" and I'm troubled by it because it's hard not to feel it's semantically close to nationalism and racism. In the anglosphere though, fertility is universally below replacement already. This is also true in countries where the cost of birth is much less than the U.S. Everyone is making up the shortfall with immigration. To follow your argument through to its conclusion we should also make immigration to wealthier countries more difficult and expensive because it comes with a corresponding increase in personal resource consumption. Still troubling.
