Your saying the Queen doesn't own what she owns because she inherited it. That's the problem.
That's how property usually works, yes. If I stole a car and kept it for many years and then passed it on to my children then it would remain stolen and liable to removal. We've seen something similar with artworks that were stolen in the 30s and 40s from Jewish families.
The land that I speak of was owned by Royal Family for hundreds of years prior to the land deal with Parliament after us Americans won independence. The debt that I speak of was the king fighting to maintain control of that land, which realistically speaking, ran up thousands of pounds.
But never did I say that George the Third sold the land in question. He simply forfeited the income that came from those lands while maintaining ownership of them.
Hence that is why you folks in the UK are only paying about 65 pence to maintain the Royal Family
Besides, the money that they earn from tourism alone...
...is roughly 350% times that of what the land would have brought them.
