Copyright infringement has been responsible in increases for 'victim', both in exposure and revenues. Theft has never (that I am aware of) benefited the victim.

Good example, but I think it's more important to point out where copyright and property law come from - that property is accepted in our society as a fundamental right, while copyright is monopoly power which our government may grant "for a limited time" "to promote the progress of useful arts".

In a more general sense, the problem is "provisioning of public goods":

Creating property where none naturally exists is one solution, but there are others (some good, some bad, depends on the type of good).
