I don't know what the original poster's answer will be, but my answer
to this is that one generally has some control over the systems on the
local net. If they start abusing broadcasts we can remove the
programs that are causing trouble. But if broadcasts can come from
anywhere there's not much that you can do to prevent them, and instead
you must defend against them. While it is a good idea for systems to
be resilient, it's also harder to implement.
