So the rule seems clear: Content-neutral bans on residential picketing are constitutionally permissible. And that would apply whether the residence is that of an abortion provider or that of a Justice who ruled that the Constitution doesn’t secure abortion rights. Perhaps Justices Brennan and Marshall (and possibly Stevens, though his position in Frisby was more complex) were right to reject this, and to conclude that people should be free to picket outside the homes of everyone (again, abortion providers or others). But the current rule upholding residential picketing bans has been useful to abortion providers as well as others.
UPDATE: For more on whether the bans being discussed in this situation are indeed content-neutral and therefore valid, see this post as to Maryland and this post as to Virginia. (Summary: Maryland law very likely invalid, Virginia law likely invalid, Montgomery County ordinance likely valid.)
