Your suggestion would be wrong because your analysis is faulty. The land is useless without skilled people to operate it. What the skilled people have done is divide the labour which has created machines that farmers can use. The trouble is they can produce enough for themselves and their machine makers by the end of Tuesday. The challenge for the rest of us is to provide something of value to the farmer so they will work the rest of the week and create an exchange surplus.

Rentiers are just the current solution that forces farmers to work til Friday. The problem is that trickle down doesn't work.

Land value tax just makes everybody rentiers and racks off the farmers because they get nothing of exchange value in return for their week of labour.
