Regardless of all the legalisms and ostensible 'reasons', just as a person, as a free human being, it is hard to believe that the government owns rainfall. It is similar to saying that the government owns all the air that we breath, or that they own the sunshine. This indicates that nobody in America really 'owns' anything. Everything everyone has is more or less a rental from the government, who is the true 'landlord'. We are all simply 'surfs', working the land in partnership and under the control of the 'Noblemen' living in the castle on the hill.
Air, water, sunshine, dirt, is there nothing that is simply God given and natural. Is it possible to buy any land, anywhere, and to be able to say, 'This is mine. I own this.'? Does everything in life have to be controlled by some government bureaucrat?
