I agree with your premise that the Second Amendment isn't self-incorporating, and I also agree with your premise that incorporation isn't really all that great of an idea in the scheme of things, but it is here, and it's certainly not going away anytime soon.
So since we have to live with it, might as well make the best of it.
In the hands of the federal judiciary, the right of free speech has become legalized porn trumping state law as well as federal judges silencing prayer in local schools and removing manger displays from town squares.
I don't think that placing the 2nd Amendment on that same path is making the best of it.
