Not Xactly.
Owner built aircraft do not require the pilot to hold a license to fly in the nation's airspace. We're talking about "uncontrolled airspace" here, not some Class C or monster Class B airspace.
It is "ours" in much the same way as the airwaves used to be "ours".

The soul and substance of what customarily ranks as patriotism is moral cowardice and always has been...We have thrown away the most valuable asset we had-- the individual's right to oppose both flag and country when he (just he, by himself) believed them to be in the wrong. We have thrown it away; and with it all that was really respectable about that grotesque and laughable word, Patriotism.
- Mark Twain, "Monarchical and Republican Patriotism"
