Firstly, I'm all in favor of watching tour players play tough(setup/condition) courses, but...
How about looking at this from a different perspective? As Pat Mucci states above..."we should cede that two games exist"...this is a true, simple fact, and should be understood as such.
Do what the tour players shoot week in and week out really have any bearing on the average player? I have argued this point of view for some time now. It is my view that the tour players have little bearing on the top amateur's and almost no bearing on the average player. Outside of Augusta Nat'l, which has become a "tournament" course, the effect of the tour players on the majority of US courses should be very little. As I have said before, if Tiger, Sergio or Jerry Kelly come to your course and shoot "many, many" under par for 4 days, so what? The member who shoots 90 every day, will still do so, long after the tour has left town. Since the majority of courses will never host a tour event, I don't see the need for drastic changes at many of the great courses.
The very small percentage that are the best players in the world should not have as big an impact as they seem to have at this point.
Why do we really care if the tour players shoot 15-20 under par every week? It shouldn't effect the average player one bit. I think some folks at GCA get carried away with all the equipment and distance issues. Ask your local PGA professional... for the 15 HDCP golfer, "PRO V1's & Giant Ti Drivers" are not the answer, LESSONS are the answer. Average players are not getting any better because they either don't have the time that is required to improve or are simply unwilling to practice enough and just want to enjoy their game "as is". The tour players are outstanding at what they do, they are far better conditioned, both physically and mentally than tour players of 20-30 years ago.
Parallel this analogy to the NBA. When Bob Cousey and the Celt's were winning every title, the height of the hoop was 10 feet. In those days they weren't doing windmill dunks and bombing long range jump shots. Today's NBA player is much different, now the guards are 6'7" instead of the centers, but the hoop is still 10 feet. Just because Michael and Kobe can jump out of the building, and Shaq can dominate as he does(while still heaving bricks from the foul line) does this have any bearing on the neighborhood guys playing at the local gym? NO!! Different game, same concept.
