With the greatest of deference to all of you who argue for more , I don't think some of us are arguing for one tee, but rather an end to the five or six boxes with the requisite tees for beginners , seniors , women , 5-10 handicappers , 0-5 handicappers , tour pros , guys who were out too late the night before (girls too LOL) , one set for touring pro's who never set foot on property , one for colege kids using anabolic aids, one for those who have old equipment , one for those with new super sized 480CC drivers etc etc etc......
Just thinking of the clutter drives me crazy, not to mention the costs and having to hire a certified air- traffic controller to figure what tee is right with current course conditions and wind for all the above named groups
Golf has gotten way too commercialized , I see the overuse of multiple teeing grounds in design as an artifice rather than a real breakthrough . Not only does it not speed up play , for various reasons, it makes for too much confusion on many levels.
