Even if the whole country was turned into one big urban area, 507 people per square km is no where near the population densities of many large cities in the world.
The Netherlands has a lot more land suitable for residential housing and a lot less density. If this is hitting "the limit", then they're not doing it right.
Why do you presume that all land suitable for residential housing should be destroyed by residential housing? There are far more types of uses than that.
There is far more to life than having a place to work and to sleep.
Except you are. Your attempt to refute the fact that the Netherlands has not hit any limit is to make baseless claims that "it has more land suitable for residential housing".
