Land ownership is an important element of long term sustainability, as in farmers carrying for their soil in order to keep it viable for their descendants.

But land ownership as in subletting and sub-subletting and sub-sub who knows how many levels up, that is not a necessary consequence of the concept of land ownership. What if only personal use was allowed? Sure, you would definitely see hoarding and countermeasures would not be without their own problems, but there is definitely room between unbounded capitalism and "property does not exist" level socialism.
