100% true. The cult of land ownership is one of the most absurd norms in almost the entire world modulo the few nomadic peoples still around. It’s not just unjust and unsustainable but simply not pragmatic, judging by all exceptions: air space, pollution, zoning, rivers, damming, emergency access etc etc.
From a human development perspective, what makes sense is to define usage rights. If you’re using the land for X I can use it for Y. This originates in the principles of refining nature: for instance if I build a boat out of a log, then it reasonably becomes my property because of the human labor that went into it. Where to draw the lines between when, where and how nature gets refined enough to get usage rights can’t easily be deduced from principles, and will vary across regions and cultures. For instance in sparse regions you can afford a larger buffer zone around dwellings. Even within a country (like the US) human lifestyle varies so much that it’s reasonable to have different rules in different places.
Perhaps people are married to the concept of owning land so much that the wording cannot be changed. But it’s already obvious that nobody owns the land, the rivers, the lakes, the air. It’s absurd that it’s illegal to walk in the wilderness because of an imaginary line in the sand.
I’m from a country with freedom to roam, so I have my bias. That said, to its credit the US has despite its strong private land ownership laws, an amazing and vast set of national-, state parks and BLM land. So from an access-to-nature POV, it’s an incredible country overall.
