Which is why Africa is so free. Oh, wait.
Central African republic, population density = 21 per square mile.
United States of America, population density 72 per square mile.
Quite the opposite. Look at all the densely populated areas, the UK, in the Netherlands. They developed democracy.
As for the US, the least populated area is in the central part of Alaska where most people live on reserve. I wouldn’t exactly call that free.
There is so much wrong with your post I don't know where to start. Big populations and especially big population density ususally mean low quality of life and loss of personal freedom. When people are sardined into tiny areas they get into each others personal space. This is particularily true when you have people of a different culture. If you have enough space to give people room to move about it won't be nearly as much of a problem. It's the old out of sight, out of mind thing. I've visited a number of very crowded places and the quality of life is VERY LOW unless you are part of the very highest income class. Otherwise things suck. Now there are a few primitive countries where the population density is low and the quality of life low as well. Saudi Arabia is one such place. But most of their land is waste land except that with oil under it. So this is not to say that low population density always leads to a high quality of life but I believe that high population nearly always leads to a low quality of life.
