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?
Trying to accomplish food security by individualizing it and parcelling it out is one of the least efficient ways of doing so. Marxism-Leninism continues to work in practice, there's no need to throw it all away in favor of repeating the failures of Saint Simone.
marxism-leninism and its direct subsidiaries are known for several catastrophic, millions-killing, devastation-famines, most notably in russia, china, and cambodia, as a result of communal farms that were atrociously poorly planned by people with no idea how to plan farms who were just eager communist beaureacrats. this disgusting track record certainly needs someone rethinking it. my system is nothing like those failed attempts.
This isn't true, though. Collectivization of agriculture ended famine in Russia and China, which were subject to regular famines prior to the completion of collectivization. Marxism-Leninism helped double life expectancies in Russia and China:
Pol Pot's agrarian pseudo-communism rejected Marxism, and is the closest thing in practice to what you're describing here.
