Every great course you guys named, would become a hell hole if you had to play it every day, over and over, without the company of gentlemen and gentle women golfers. Sure, you could go out everyday and bat the ball around your dream field of play, but if you had no one to play with, or were stuck in an odd environment that went against your personality grain... well you'd either need to be a socio-path or a very mean, solitary, and pitiable person...
I personally have to disagree with your statement.
During my life I have had a couple of courses that I almost exclusively played over a 12 to 18 month span. And both courses never grew tired to me. One was Algonquin G.C. in St. Louis. This is a Foulis design with some updates by Silva.
The other course was A.L.Gustin, in Columbia, Mo. and owned by the University of Missouri. For one year I worked at a private club in town, The Country Club of Missouri. At that time C.C. of Missouri was the home course for the men's golf team. I played that course less then 10 times during that year, including a summer without any classes. However, I did play A.L Gustin almost every other day.
This course is open to the general public without any restrictions and still very inexpensive even for those not associated with the university. I never grew tired of playing this course. I had a few regulars that I often played with, but we also played quite often with walk-ons.
I agree that there are some advantages to playing regularly with fellow members. But if the circumstances are right, I think playing regularly at a public or muni can also be very enjoyable.
I would also agree that if one was forced to only play Bethpage Black, and if each round was close to 6 hours, that could result in forcing me to quit the game. But I answered this question in the hypothetical, only considering the course.
If I were forced to choose a course, taking into consideration the course, the conditions, the price, and the pace of play among other things, I likely would then not choose Bethpage Black, or The Old Course. Although, I may then choose The New Course at St. Andrews. And for the US, I may just choose my old haunting grounds in Columbia, MO - A.L. Gustin.
This way I also get my Missouri Tiger's football, basketball, and baseball, and my favorite pizza in town - Shakespeare’s.
