You're still equating all "habitable" land as equal. I'm sorry, but land in northern Canada or the Saudi Arabian desert is not equivalent to land in Hawaii. Only in one of those places can you enjoy being outdoors year-round; the other places will literally kill you if you stay outside for very long. That's exactly the main reason there's reclaimed land in places like the Netherlands. No one cares about reclaiming land in Siberia because very few people want to live there (and those that do, likely live there just because of work and because they have no easy way of moving someplace nicer). Finally, those people living in Siberia likely do not have that much living space per person, certainly nothing like the palace of Versailles. More likely, they live in mining towns or small cities, in small houses or apartments, with most of the land area being unused.
