We already have plenty of laws on the books. We cannot rob, murder, rape, etc. If we can't do those things, then when we use a gun to do them, we commit a crime.Laws are designed to protect the greater good. Total freedom would be anarchy as anyone could do anything they wanted. While I don’t like licensing, I understand the reasoning behind it.
We also have the right to defend ourselves, thus the need for guns. Why regulate a constitutional right that shall not be infringed? Isn't regulation = infringement?
When it comes time to get on a plane, the airline can always say, "we don't allow folks to carry guns on our aircraft". They then are exercising their property rights. I then choose to carry my gun and walk or drive to my destination, or I lock it up at home and buy a ticket.
