Watch yourself. You've slid all the down the slope and almost said the "D" word.
WE ARE NOT A DEMOCRACY!
My rights are not subject to anyone's vote even if they go thru the entire amendment process and are successful. My rights are mine by virtue of my birth and are unalienable. Government may choose to violate them, but they do so at their peril.
I can agree in principle, but in the real world no man lives unto himself. By agreeing to live as citizens of the US and thereby enjoy it's protections and benefits we accept an implicit contract with government and agree to the limitations the Constitution allows government to impose on some of our natural rights. The Constitution grants certain specified powers to government which necessarily impose some restrictions on the exercise of our liberty. In theory at least, those limitations are only those which are necessary to allow government to protect the common rights of all citizens. To quote the familiar old saw, "your right to swing your fist ends at my nose". IOW, it is not reasonable to expect to exercise every right to the degree you may feel entitled to if that degree substantially infringes upon another person's rights.
In regard to Gilmore and his refusal to obey the government's air travel regulations, It is unquestionably within the government's Constitutionally granted power to place restrictions on commercial interests which operate across state lines. Therefore his 10th amendment unspecified right to travel conflicts to a degree with the government's specified power to place conditions on his use of the regulated airline's services. In that case it is my opinion that the safety of the traveling public and the duty of the airline's owners to obey government regulations overrides Gilmore's right to unrestricted travel. He is free to travel across state lines by non-commercial means without showing ID, but in order to use a regulated commercial service he must abide by the government's rules which govern that service. As I said previously, the only violation of Gilmore's rights that I see is the government's denial of access to the regulations he refused to follow.
