Why would housing become unaffordable if the state intervenes? The purpose is precisely to control affordability. Prices are controlled for social housing, and flexing supply allows you to influence the free market prices.
Supply is always less than demand in dense cities/countries, leaving it for the 'invisible hand' only ensures that the whole market is unaffordable and/or gentrified. Like what we are seeing in this news piece.
I don't know exactly how it works here in the Netherlands, but as far as I understand the government leases land to the constructors at its own pace, with strict quotas on social housing, to let vs to buy ratio, and free-market properties. It isn't perfect (massive bubble on the free market right now) but seems to work well enough.
