I wonder about this myself from time to time. Like take tobacco smoking as an example. Who owns the air we breath? Is it considered "aggression" to pollute the air with substances which are noxious to the other people effected? In principal it's the same with air-waves. Who exactly has allodial title to the air[waves]? Is there (or should there be) such a thing as adverse possession (eg. squatters rights) in this context?

Thing is, whether [American right-wing] libertarians are willing to acknowledge it or not, there is such a thing as public property (aka: common pool resources). Air and water are the most obvious examples. This is where [American right-wing] libertarianism's capitalist myopia puts a wrench in the gears, and where folks like Elinor Ostrom make vastly more practical/realistic sense.
