For instance, trees essentially power the entire terrestrial water cycle. Without trees all the water rains out within a few hundred km of the coast. Trees (far moreso than simple evaporation) are responsible for pushing that water back into the air-stream. Isotopic analysis confirms that 80% of the rainfall on land is caused by transpiration, and most of that is trees. https://www.nature.com/articles/nature11983
This explains why deforestation causes desertification. Cut down the trees and you get a continent-wide desert.
These dynamics aren't well-captured by the present economic system, which only sees "valuable real estate" being "taken up" by trees.
As long as plantation owners and/or illegal loggers do, then all your argumentation is moot.
Yes, there is. Trees take a up valuable real estate. As long as people can do something even remotely profitable with land they own, this can not work.
