It's getting better in the UK. At a number of the top courses you can play off the back tees if you inquire discretely beforehand and have a reasonably low handicap. Some (e.g. Turnberry, Cruden Bay, Portsalon) let you play from where you want to, regardless.
My take is that the whole "medal tee" cult goes back to the days when medals were something special, and there was a sort of ritual in going backwards from where you usually played to exotic sites with unfamiliar angles to the fairway and then to the green, all with a card and pencil in your pocket. Quite frankly, I still enjoy this ritual, and if I were allowed to play the medal tees every time I played my home courses, some of the mystique of the game would be lost.
