If this concept were rewritten, from the ground up, without any thought toward prior versions of it:
I think it would start with:
How much land, exactly, at a minimum, does every single person need, to sustain themselves? This amount of land should be given to every single human born, for free. The amount of land is actually small: it’s only the amount of land needed for a sustenance garden. Or, a sustenance garden, a few animals, a bed, a toilet. This is a very small amount of land. It’s certainly not even an acre or a half acre. In the middle ages, a sustenance garden was about ten feet by fifteen feet, and usually was filled with giant turnips because these were the most efficient use of a sustenance garden. Anyway, the basic kit provided to each newborn human by their worldwide fellows should be: just enough land to sustain themself as a native, and, just enough farming education and seeds and baby animals, and basic supplies for a bed, a small shelter (single enclosed small room simple shelter), simple basic toilet/plumbing/running water and/or outhouse system. A basic minimum size of land for each person. Maybe a quarter acre each? A third acre?
Your system would obviously exacerbate it because you've described individual subsistence farming.
