Actually, I think it is very, very good. This focus on the "home" could allow the Supreme Court not only to rule on incorporation, but also to take an initial stab at "bear" as in "keep and bear".
The Supreme Court should find that it is ludicrous to expect that counties, many of which hold title to public roadways, can pass a blanket prohibition against bearing arms on such roadways.
Why bother having states when we can have centralized judicial control of local policy issues?
