I don't think I called you "thick," or even made an allusion in that direction, but if I did, I apologize. The last thing I want to do is insult you.
I'd say the air is "owned" by the sun as well, since it was created through the same fusion process.
If you don't own any property, then you you sure as hell don't have a right to live on anyone else's property, unless they grant it to you. Just as I could homestead a cubic acre of air with a permanent air station, I can do the same on the ground. Air is so plentiful that there is no need of a market for it on earth (except in terms of airspace for planes, ect.). Land, on the other hand, is not, so the threshold is high enough that the market can get involved and generate profits.
The sun bit is not really the core of the argument, merely speculation on my part. This is my attempt at an actual proof:
Will my ability to own a sandwich be drastically different under a free market system? I should hope not... Physical property rights work extremely well as is, and minus the steps of taxation and regulation, they are completely morally neutral. It is precisely that filling a need is morally neutral that having property rights must also be morally neutral. If I steal property from an old woman or a tribe of Native Americans, that is clearly immoral, but if I homestead a plot of unused land with my crops, I am not infringing on anyone else's rights, and I haven't done anything wrong. In fact, I'm creating productivity in the economy, which exerts a number of positive externalities on society as a whole.
If it's not an immoral action to own apples, then it must not be an immoral action to own an apple orchard, because it is impossible to have apples without any apple orchards. Similarly, if I can own a kitten, I must be able to own a mother cat. If it is morally permissible to own coffee, it must be morally permissible to own a coffee maker. If I can own a car, I must be morally allowed to own a garage (whether or not I choose a DRO that prevents garage ownership is beside the point-- I can always leave my DRO). If only some people can own apple orchards, say the State, or the ones elected by some kind of free-market, democratic union, then the moral rule is not valid because it is not universally applicable.
Furthermore, if it's not an immoral action to own an apple orchard, it must not be an immoral action to own the land in which the orchard is contained for precisely the same reason. If it is morally allowed to own heroin, it must be morally allowed to own poppies. If it is morally permissible to own poppies, it must be morally permissible to own a poppy field, and the land that poppy field is on, and the amount of water, CO2, and sunlight needed to sustain it.
Which is not to say that any of these things are moral per se, merely allowed-- morally neutral.
