You forgot soil depletion, loss of pollinators, and system ecological collapse, but yeah.

Food production per acre has increased by ~4x over a century, but that's the only 4x we ever got and the only 4x we'll ever be getting. We've been at diminishing returns for decades but will soon peak and experience lots of bad effects from unsustainable practices.

It is not correct. Here in the Netherlands we have Avery efficient and sustainable food production (vegetables and fruits). The systems are getting so efficient that in 20 years from now it is expected to have almost fully automated production factories which can operate indefinitely (theoretically) And our export is big. When other countries adopt our technologies we can provide food for billions with just a tiny environmental footprint. So there is absolutely good progress made in that field.

Efficient, but unfortunately not sustainable at this scale and intensity. E.g. our soils are in a bad state, see the recent report from Planbureau voor de leefomgeving.
