Sometimes countries need cash, and maintaining the land is not worth it, and someone is willing to buy. Should Denmark have sold the Virgin Islands in 1917? It was put to a referendum, and the people said yes. Napoleon also needed cash, so he sold a lot of useless land in North America to a willing buyer.
