>The innovations aren't better versions of things we had in the past, they are more so unique new inventions. Plumbing is not electricity is not globalized food chains is not computers.

This is only sort of true. Plumbing is an improved version of a well pump, which is functionally (if not technically) an improvement over walking down to the river for a pot of water. Globalized food chains are mostly improvements on the supply chain we had (boats got faster, so things can travel from farther away places more quickly, refrigeration got added to existing modes of travel, etc.).

>Also we don't need to make more land to have more people. We can make more habitable living space within the same amount of land area, especially in countries like canada and the USA where we dumped a bunch of low-density housing absolutely everywhere, we just choose not to do that.

I didn't mean to imply that we can't increase housing density. But I think it's clear that having 2.3x more people than 1950 means that all else being equal, people will need to settle for less land. There's just more demand per square mile.
