The marginal cost to produce a nights worth of stadium use is nonzero -- staff, performers, and depreciation if nothing else. So the users should pay that.

The marginal cost to produce data (or software) is almost nil -- hence the price should go to nil as well. THe only reason for a society to force the cost to be non-zero via licensing is to incentivize the creation of the data, but the government is going to do that anyway, since they need the data to function.

(The marginal cost thing is why we need copyright and patents -- we need to impose non-market controls, because otherwise price and profit go to nothing and there is no incentive to create things which have marginal costs of nothing like sheet music and new molecular compounds. Yes, there is some irony whenever a capitalist argues for intellectual property -- save my market by non-market rules!)
