Plenty of examples on both sides of that, even in the US there’s vast swaths of land that can’t be privately owned for example try and buy a navigable river or land below the ordinary high water mark etc. https://en.wikipedia.org/wiki/Navigable_servitude Similarly eminent domain severely limits the meaning of private land ownership in the US.

Why is it that property is taxed less than productive work? Someone sitting on their ass doing nothing but sucking resources through dividend payments has that income taxed less than the workers' income who did the work that generated those dividends. Why isn't the reverse the case? Heavily tax passive income, and lightly tax active income. Incentivize productive activity and penalize rent-seeking parasites?

Places with predominantly private ownership can be and are prone to famine, and/oril genocide, etc. as well.
