"How is <x> about interstate commerce?" is a question that's been asked by reasonable people for many values of x that've been before the Supreme Court. In other words, don't ask me. Ask SCOTUS. They've used the Commerce Clause to justify regulations on activities that were far less obviously about interstate commerce than zoning is, most famously in Wickard_v._Filburn, which restricts a farmers right to grow wheat on his own property for his own consumption, which, according to the court, is indeed an example of interstate commerce. My statement, in other words, has nothing to do with my own interpretation of those rulings. It's merely an acknowledgement of them. It's not difficult to think of ways in which local zoning restrictions affect national commerce. And that's been good enough for the Court in the past, it seems.
