You do not need to go to "ultra high" density, à la Manhattan or Hong Kong.

Once you get to densities of Paris, Stockholm, Amsterdam, Munich, Brussels—in the 50 people per hectare (20 per acre) range—there are diminishing returns:

I would not call any of those "ultra high" (though perhaps others would?).

Paris - the city itself - is actually surprisingly high density, almost as high as Manhattan if you do not include the two very large 'Bois' (woods) that are technically part of the city.

I don't know where they get that 50/Ha figure. Paris is more dense than Seoul, with just over 200 people per Ha, or ~20k/km². Figure would actually have been higher at the 1999 date of the cited source, too. The city is (slowly) losing people.
