Land Ownership.
Landlords are a menace. Pricemanipulated scarcity of housing for profits with houses and properties sitting empty while homelessness runs rampant is disgusting and obviously not an attribute of an enlightened society.
I say this with not a solution in mind but seeking a 'best way'.
State Property historically tried to address this. It may be better, sometimes, for homes to be of the government than land held by few wealthy individuals and businesses. But, in all these situations, the home is not really that of the being, it is a property of an overlord. Even buying a property in capitalism does not elevate one to actual rulership of said area. Taxes must be constantly paid to larger monsters to continue to hold the property and it must adhere to the rulings of the county. All of that feels wrong to me.
Imagine if there were no humans. I would just find a place by the river and some natural distance around it, shaped by natural features, is how far I would often be and consider the domain for which I am responsible. It is my responsibility that the beings in this area, creatures and plants, are happy and content and growing healthily as people and, through the communication coming from them, feedbacklooping in to the environment to further improve it's overall emotional energy. So I claim specifically the area I find sacred and would like to be proud of; because it is the appropriate size I can be responsible for.
Somewhere in humans conquering each other, staking claims for profit, and monetizing each other, real reasons for territory, not tied to money and the military power to enforce ownership, were lost. Humans also feel a need to tailor their rules that affect everyone to the worst beings among them. Of course they need to because, otherwise, such 'worst humans' would get away with what they shouldn't.
Land ownership, among humans, has warped far from anything pure and good. So I am lost on how best to structure land ownership in a realm of humans.
For sure the landlords and property scarcity issue needs to be different. Perhaps not full State Property but for the nation to have enough housing in each area that people, with no restriction on income level, can, at baseline, have a home. I personally get government benefits for being a crazyperson and it is just enough to live on with no excess. So I am stable yet am growing myself into and producing things that will get me out of poverty in to a realm of excess and ability to spend on what I choose. I think housing can work healthily the same. Baseline housing for all people should be a reality. People will still work to rise to something better if that is their destiny. Landlords should be optional, and will probably fade except for the rarest actual worthy landlords with properties people WANT to rent for some reason (not NEED to rent).
I see humans far from the ideal. But this is a start.
