Bada bing,... nailed IT !!!Certainly we'd all prefer lawful citizens who carry firearms to have a little proficiency.That's not the question. It's truly a straw man
Instead, the question is do we trust government to decide who is "fit" to carry and who is not. If the answer is "no", then I think someone is already onboard, or very close to being onboard, with Constitutional carry. If the answer is "yes", someone then believes in mandatory licensing under government control. Which would necessarily be at the state level today, with every state going off on its own....unless someone prefers to trust federal government under Joe Biden.
I don't see how those of you who prefer mandatory qualification can have what you desire without also giving over to government the right to determine the standards.
We have already seen what some state governments have determined to be reasonable. Again, the example of New York is real. They're fighting all the way to the Supreme Court to retain their state government's "right" to decide what is reasonable. There are other states as well who have used licensing authority to trample over 2A rights.
And this is not a straw man argument.
