of course people own land,don't we buy it and out a house on it?

To be more accurate, you do not own the land anyway, you just rent it for limited time aka 99 years... What you are buying is the right to use it as a place where you can build a dwelling, or in case of agriculture you work it or plant something or graze animals. You never own it in technical terms. You may pass on said rental or on sell it but you never own it.

As such that is why you can be evicted or the land re-purposed by the entity we as a society grant such privilege.....for a fee or reward of course.
