It can be argued if this is caused by the government, but the Dutch seem more maintenance-minded than most other countries I visited. Probably caused by all the dikes: if not maintaining something properly will kill your entire village, you have a lot of incentive to become very good at it.

As far as I know (I am not a farmer, nor do I know any greenhouse farmers very well), lots of it is private capital though.
One of the biggest banks in the Netherlands (Rabobank) has a (positive) reputation for financing farmers and other agricultural firms. (also a negative one due to the LIBOR scandal, incidentally)
A lot of these systems require enormous (and growing) up-front investments, not feasible for small independent operations. There are a lot of family business in Westland, but they require massive mortgages and/or loans to keep up with the times (and the investments that they require). There are fewer and fewer small farms and more and more 'mega-barns'.
Little space is needed, but a lot of it is high carbon and high capital.
