I equate airwaves as the public road.. and cell phones/minute plans as the cars we drive on roads and the gas.
The airwaves however are free though not unlimited in capacity, and therefore it is reasonable for government to regulate their use to be sure everybody has access and no single monopoly will have ability to control them. But the use of them is quite capably handled by the private sector and no involvement via government is necessary other than in the necessary interest of national security.
The roads are a little different because they do require heavy construction to create them and serious maintenance to keep them usable and safe. And since it is hghly impractical, even impossible, for everybody to create their own private roads to go where they need to go, or for a private company to have control over who travels the roads, people turn to the social contract to pool their resources to have public roads accessible to everybody without regard to political affiliations or socioeconomic status.
The government does not "give" us roads. A free people empowers the government to create them for the benefit of all the people. The 'liberals' among us see this as benevolence of government and we therefore are all beholden to government (i.e. another reason to despise liberalism.). The 'conservatives' among us see this as social contract to accomplish a common goal to benefit us all.
Even those who don't drive benefit from the roads because the service people they depend on, the goods and services they must have, and the security they need all utilize those same roads.
