Not at all, just that property/land ownership before our democratic system was implemented should not be recognised.
To imply that we have to abandon all modern ownership rights because we reexamine historic claims is simply false.
And who do you give this land to?
It's an unworkable position and would tear up statute and rights that we enjoy in our democratic system, particular as due to our democratic (constitutional Monarchy) system those rights exist at all.
I understand your perspective, but also understand that the ideal is rarely the utopian solution it appears to be, and is more often than not the opposite.
