And lets be honest, the interstate commerce definition has been hogwash since case law got on the books stating that intra-state sale of grain could be regulated by Congress because of some indirect potential to affect markets across state lines; and such jurisprudence being utilized as a desperate lynchpin to try to keep individual states from unmaking the Federal level gun control framework.
I can play word games and run rings around the English language too, however, my goal is not to stretch what's on paper to create pretense for interfering in every U.S. citizen's life in ways that make it easier for more and more liberties to be stripped, and for the actual force of law to get increasingly hidden from the plain English meaning of an a reasonably literate individual.

This is kind of the same question as the free speech issue on social media platforms. Where do we draw the line at what remains a public utility? There is already an extensive framework of laws in place regarding peoples rights to use a motor vehicle for transportation, including the right to file a legal appeal to one's license revocation. Flying in a plane should come with the same rights and responsibilities.
A legal designation of a common carrier is a significant burden upon the freedoms of those supplying a transportation or information service - it is not a step that is taken lightly by Congress. And even that designation isn't all-or-nothing; common carriers can still refuse to provide services. For example, even the U.S. Mail can refuse to transport hazardous materials.
