If you have lived with other people (and you have), then you know the room-mate problem. As the number of room-mates increases, so does the pressure to be responsible, share, and get along with others. A big household may be jolly, but your freedom is limited. Lounging in your underwear or neglecting dirty dishes invites conflict.
Consider this in a global and historical context. Anthropological and historical research estimates that in our first 200,000 years, human population grew from less than 1 million to about 1 billion in the year 1800. In the next 200 years, population grew to over 8 billion. That's not sustainable.
Population increases and resources dwindle. At some point we won't be able to feed everyone. Technology helped for a while but resulted in environmental damage which now intensifies the problem.
At this point, the climate denialists will jump in, like alcoholics, justifying one-more-drink. I'm not riding with those assholes, or the religious nuts who want to breed like rabbits until we drown in our own feces. No thanks. Back in 1800 one could travel to exotic lands and be "free" on the frontier. You can't do that now. The world is all filled up. There's no frontier. Some believe we can colonize other planets. It's way harder than they think. I'm not sure if I should wish them good luck or good riddance.
Our best hope is to humanely reduce population by making incentives to NOT reproduce, and allow our numbers to decline gradually. Failing that we can let nature to do it for us with plague, famine, and war.
I know that many of the "Amerika-Freedum" tribe will reject this dire scenario. But even they should see that if they want to do as they please, it would be easier in a world with less people. A world with some room to move. Remember the room-mate problem. The solution is so simple even a fool can understand. If you want more freedom, you need less people.
