... (1) in a moneyless system where land is free, a farmer or artist can be convinced to allow their parcel to be put to better use. ...
(2) As far as inheriting land, as I suggested earlier in the thread, a possible rule of thumb would be land could only be passed on to your current spouse when you die. Any other relations after the spouse died would have no power to keep the parcel from returning back into public circulation.

I am a popular "artist," and I like the inspirational view of the distant mountains. What would induce me to let someone farm my land, even if they agree to not use pesticide?
The obvious answer, (You said you will not force everyone to abandon money.) is: I will accept rent payments monthly for someone of the money using group. I assume that I am allow to buy a car with those payments, etc. even though occupying land that cannot be sold. This will happen with most occupying high fertility land. A money rich person (or corporation) will rent a few dozen adjoining parcels and with that scale use tractors, not horses, to till it, buy fertilizer cheaply in bulk, not just the low quality each can slowly make with an organic waste pile, etc. I. e. this is desired by all as food production per acre will greatly increase but mainly benefit the money using group who can buy it.
For discussion only, I have assumed there are two systems co-existing, but I have in prior post noted that the two systems can not co-exist. The above is yet another reason. I. e. All the good farm land will be controlled (by rent, not ownership) by the wealthy of the money using group. Remember, even a 5,000 member commune is too small to make steel, so must buy its nails, hammers, saws, and complex to make pharmaceuticals from the money using global population. Thus presumably, the commune members are allowed to sell some produce, like tomatoes to the money group, to get essential things they can not make. (For practical purposes, the no-money people become serfs, tied to their land but do not control it. I. e. the self-sufficient, and thus powerful money using group will exploit the others, as they do today.)

The land available for someone forced off the land he was born on when the last of his two parents dies will be the poor quality land no one wants to farm. (Why it is still on the "available land list") However, when the last of a couple that has spent decades improving the productive of their land (like the Almish have as they hand it down thur many generations) does die, some good agricultural land will come available. Who gets it?
Again the answer is obvious (assuming your prior statement that land goes on a first to ask for it basis):
The ambulance driver, who took the 2nd dying spouse to the hospital gets this good land, as he goes straight to the land claim office after delivering that last spouse to the hospital - Gets there before the official in charge of new land assignments even gets the death notice. After filing his claim the driver immediately re-enforces it by going to land and planting some seeds, etc. Thus there will be no shortage of "no-money" people wanting to become ambulance drivers.
