I've seen this argument alot--it's only .00001% that can hit the ball so long, take advantage of technology, etc...
But I don't think that is the point. In any field, the standard is set by the best. In golf the elite touring professionals have set a standard that is now incomprehensible to everyone else and this is DIFFERENT than they way things used to be in some important ways.
50 years ago it was the precision of Hogan or Snead that the 10 handicapper couldn't duplicate. The avid golfer could tee off from the same tees and length was not the defining issue. Irons were hit about the same distance as the pros.
Watch old Shell Golf matches and see the guys (Palmer, Nicklaus) hit 7 irons from 145 yards--it was amazing how they shaped shots and controlled distance without hitting all out. Nicklaus of course could hit a 7 iron 180 back then if he wanted to but at risk of mis-hitting a shot with far more dire consequences than today.
Today, its smash mouth golf that is fundamentally different than how the game was played for 500 years. While controlled length was (and should) always be rewarded, it's not the same anymore.
What is so sad is that while 50 years ago good avid players could play the same course and attempt to duplicate their heroes exploits, today it is such a different game and only the elite pros will ever know what its like to hit 250 yard three irons
Worse, for new golf courses and design as well as for young players coming up who want to be one of those elite one day, that .00001% is setting the new standard for the game.
