Is There a Win-Win Situation in Ireland?

Ireland is the least densely populated country in Western Europe with the exception of Norway. And we have amongst the highest land prices. So it means that at the core of the land market is gummed up. Why is it not being made available to try? Because it's been hoarded by developers. If we ignore that, they will just simply sit on it. But what is good for the collective here is that we make land available. Now who pays for that? A number of individuals who happen to be developers. The state doesn't do that amazes me even on an optics idea.
