On some level that sounds reasonable. But guess what? The seat of government is in DC. I should have a right to freely travel there for a redress of grievances. And I should be able to do so with all of my rights in tact.
...what is to stop them from saying that those CCW permits must have 40 hours of training? Or can only be issued to those above a certain age? Or other requirements?
Not all states have the same requirements for receiving a drivers license, but all licenses are recognized in every state. States should issue CCWs as they determine. And they should honor the CCWs of the other states.
And should you have the right to do that in the White House or the Capitol?

Not really, no. Kansas is an agricultural state. You can get a drivers license, with restrictions, at age 14. That license is not recognized as valid in Missouri or Illinois or Colorado.
Drivers licenses are valid in other states because other states choose to recognize them. CCW permits are recognized in other states when those states choose to recognize them. If one or the other is not recognized in a given state then there is nothing the federal government should be able to do about it. It's a state issue.
