> The point of looking at the monetary value is that it's a way to quantify how unavailable they are. Land costs money. Where land is scarce, it becomes expensive. Where land is abundant, it's cheap. If landing slots can be acquired cheaply, it means there is availability.

Sure, but I think you're missing the point about the "non-availability." I don't think the cost shows everything.

When there's lots of slots available then the price will be low. When there's few slots available then the price will be high. When there's _very few_ slots available then prices are harder to compare. There's an upper limit on what a company will pay (a slot can only provide so much profit, after all, even if you expect to own it for many years). Prices will presumably start to depend more on who's bidding for them and what deals can be struck.

Free market economics only works if the market is able to respond (i.e. it's relatively liquid).

Thanks for explaining my point better than I did :)
