So is the largest contributor to the problem just lack of land? Seems like most of the other problems from the article can be solved with money, but a lack of land makes it hard to build anything

More land can be “created” just by building taller.

Nope, our spoil isn’t dense enough for it. We cannot build higher then what you see in Rotterdam, because the building would just fall over

Hold the phone… Are you saying there is no bedrock in the Netherlands?

Not in the part that’s under sea level. Can’t have basements there either
