The rules of golf are far to complicated for a child who loves to compete to learn. I have never seen a sport so full of innocent and intentional cheats. The parents who follow along are ignorant and insane. It is the worst of all sports to push a child to play.
Agree with the rules part, but not the ignorant/insane part.
Golf has lots of rules.
Golf is hard.
Golf requires patience.
Golf needs a dress code.
Golf is a parents game.
etc, etc.
Bottom line is that golf is not exciting to the vast majority of kids. I'd say maybe 98%. Even if a youngster has remarkable talent, they may not pursue the game.
But, it is
golf. And now I ramble a bit. Golf is not "professional" wrestling. Is the problem golf as it is, or golf in relation to other sports and activities? And, if the latter, then is there any place left for golf at all, anywhere? Golf is not computer games shoot 'em ups, NFL bash 'em in the head, or even "you da man" or "in the hole." It's just a game for average folks to go out and play. Some average people like to bowl - same deal. Sure, golf has lots of rules, but that's golf. It's challenging physically, skillwise, and mentally, both in the physical component and in the "rules" component.
You mention "remarkable talent." That, in my view, has nothing to do with golf and private golf clubs. A few guys or gals with remarkable talent may be able to make a living playing entertainment (tour) golf. But that's only because, I would suggest, that there is a large audience of recreational golfers who enjoy the game for what it is. "Remarkable talent" is only worth what the rest of us will pay to see it as entertainment.
Golf itself may die off except for the weird few, but that's a different question from the private club question, as I see it. Assume there is room for golf as a pastime for the average person. What role will the private club play?
For me, a private club member for 18 years, the club is a place where you can go and "get a game" with friends. Where I live, the public courses don't offer that sort of option. On the other hand, a cousin of mine is an avid golfer and lives in an area (o.k., it's the Pinehurst, NC, area) where there are lots of great daily fee options. He belongs to a well organized group of golfers named the "Whatevers" who are members of no private club but organize frequent games, weekly at worst, at very nice daily fee courses. In effect, they have a club - a private club, if you will - but do not have to worry about supporting a club with a course and other amenities. In the right place, with the right people, this is a "private club" option that could be the future.
What I am suggesting is that the future of the private club will depend on the private golf clubs' abilities to give folks an easy, enjoyable social exprience, primarily or exclusively for golf, as compared with other golf options.
