Since I and most everybody I know will never answer a call from a number not in their address book as a direct result of robocalls, I'm not sure that this is a huge issue.
If, for instance, my water company called me with such a notice, it's not likely I would actually hear about it that way, because I'd assume it was a robocall. I'd more likely hear about it through other media outlets.
I know several people with kids, and I have kids of my own. They're no longer young enough for this to matter, but even when they were, I still ignored calls. The main difference was that I actually bothered to listen to any voice mails unknown callers left.
