Lmao that's an intentional misunderstanding. They are obviously referring to land which has been claimed by a private entity just for the sake of 'land value' because this leads to hoarding and unnecessary scarcity. If one develops a farm on that land, then they should be entitled to a significant share of the profits reflective of their investment of time and resources, but those who dedicate labor to working that land should also be entitled to an ownership share.

The premise is that land should not be snatched up and 'owned' in its entirety, especially for prospective reasons, when the 'owner' is not providing any value through their 'ownership'. This is just greed institutionalized.

In reality, all land belongs to the earth and we are just a bunch of monkeys fighting eachother over fictional rights to that land in the pursuit of power and influence over other monkeys.
