Thanks for pointing out the population problem. This consideration leads to more interning thoughts.
If we can feed the world today with less people farming than before. We can grow more food per acre (which will be higher quality) with permaculture, and not to mention that more land will be utilized for food production. There should be no problem feeding the world.
It's not a problem of food production in my opinion but more a problem of population density or population distribution. While the industrial revolution might be the start of these population densities, fiat has subsidized thier continuity long after their sustainable growth limits. Permaculture, and Bitcoin will make a decentralized world (again? More than ever before?).
