It’s not just selling land; it’s extracting value from the land.
Like, say, oil drilling?
The more oil you extract from the land, the lower the price goes. When it costs $70/bbl to drill oil that is being sold for $30/bbl, how much volume will it take to clear $19 trillion in profit?
Careful farming is “extracting value from the land.” Selling off our oil is eliminating value of the land. Some years ago my husband inherited land in Southern Illinois. We were offered $1,000 an acre for the underground coal rights. The coal was about 800 deep so we figured it would not hurt the surface so we sold it. Later we also sold the surface land and were paid less because the coal rights were gone. But the point is the coal no longer belonged to us. Same with oil drilling and selling which was also happening in that area. Farmers would receive 12% of each barrel extracted. If the government did the same, we would get 12% of the oil value and someone else would get 88%. Not a good deal in my opinion.
