Ben,
I agree with certain aspects of your last post. But just because a set of tees are present doesn't mean you have to keep score. For me, this isn't about "pandering", it's about signaling in a very basic way that kids are welcome on the course. I wouldn't take it for granted that they are. When I was a kid, that was not the way of the world. As I said in my last post, we didn't even go to the local muni until we were 12 or so. We went to the par-3 course. If more such beginner-friendly facilities were available, there'd be much less need to argue over family markers.
Maybe the world has changed, but for me the kind of unstructured play you're talking about never happened within a regulation golf course during "normal business hours." I wish courses (and, just as importantly, their patrons) were more receptive to that, but too often that's just not how it works, at least not around here.
