And what would you'r solution be? Take from them the houses they worked their whole lives to acquire and put them in elderly homes? They have paid their share to society by providing the taxes for 65+ years that they have worked and brought us where we are today.
Those homes are not vanished from the market. They will be inherited by their children and so on.
Land taxation is by my opinion inherently bad for that specific reason ( if they have only one piece of land )
The problem is that we are pilling into cities where land is minimal and thus the market works in supply and demand.
Hopefully as years pass, where remote work is more and more accessible you can be owning your own 1 euro or whatever home in any area and not worry about limited land.
