Thanks for the positive mention - half a dozen out of 300 ain't too shabby...
For the most part I'll second Bob Crosby again. Anyone who thinks the USGA isn't already influencing architecture is kidding themselves. Sometimes it's overt, sometimes it's simply in its approach to the game.
Responsibility is a tough word to use & define in this context.
Does everyone have a responsibility to contribute positively to everyday life? I don't know, I believe in personal liberty & if anyone wants to sit around & do nothing, that's his or her choice - just don't ask me to pick up the bill.
Similarly, the USGA can test golfers anyway they see fit, and golf manufacturers can even do anything legal they desire in their pursuit of profits - just don't be surprised if their actions are often misinterpreted by ignorant (knowledge-wise, not etiquette-wise) observers, whether it's the media, your local greens committee or Joe Six-Pack Golfer.
A simple word or two that gets reinforced periodically would go a long way toward helping things out, IMHO.
