I think your argument would need to be that it has no sympathetic victims.

In any case, local monopolies that come from land are a common theme, not just for ski resorts. It's literally what land ownership is--or even just a 99 year leasehold, even with no freehold 'owning'.

The usual solution is property taxes (or land value taxes) to have the taxman soak up the benefits of any monopoly.
