You could comfortably fit that entire 7B population at suburban densities into a
land mass the size of Texas.

It's not a question of finding space. It's a question of providing 7 billion
with the same standard of living currently enjoyed by only about 1 billion.
That's a seven-fold increase in resource requirements.

As long as most of the population lives in dirt, you can afford to keep a few
people fat and rich, but if you want everyone to have the same standard of
living, you have to either settle for a very modest standard or keep the
population small.
