This is a false analogy because unlike money (representation of value), land is not consumed and disappear. A better analogy would be: your grandparent barged

This is a false analogy because unlike money (representation of value), land is not consumed and disappear. A better analogy would be: your grandparent barged in to a persons house at gun point, demanded him to hand over his house. The owner obviously resist, and your grandpa tells the original owner that he will be given his house back in a couple of years(legally signed) to ease the resistance. This paper was also signed "with the current owner of the house", in mind(in case grandpa dies). Now the original owner lives on the street, his grandchilden the same. Each generation have always asked "when would you live up to your promise?" to the descendant of your grandpa (current owner of the house) each year. Now you can of course discuss if you should give additional compensation for their suffering, but the original contract still stands, and you've always been obliged to follow it. It's not about blame. disclaimer: I'm in general in agreement with you that I don't think a child should be blamed for their ancestors sins.
