As has been pointed out, that really depends on how you mean "national channels" differ from others. Many local versions of channels like Discovery and MTV are quite popular in the Netherlands and can rival some of those in the list above.
I'd say the number of general entertainment channels isn't completely dependent on the number of inhabitants in a country. If there is a possible niche with a certain critical mass, it will be exploited. Smaller countries tend to have more channels per capita, but the money spent on each channel will obviously be smaller.
Cable penetration is very high in the Netherlands, so I assume many would think of the channels on analogue cable as "free" or "national" channels, even if you have to pay to get them.
SBS and RTL will launch new channels in the Netherlands
This leaves us with the question: don't we -- in a country of 17m people -- have enough national tv channels?

Is cable subscription-free though? I thought it was pay-TV in the Netherlands?
