I think you guys cannot even see the point. Golf works great for about 8M old white guys like us, for whom it is great just the way it is. Why change? Why should anyone ever want something different that what is traditional golf?
Does the NBA fight street basketball? Stop anyone from playing in the driveway? Does the MLB fight softball? Why shouldn't there be cheaper, easier versions of golf to access for the masses? Heck, if there were, more folks would enjoy the essense of the game - hitting a ball with a club. Maybe some (like Japan) never get out of the Top Golf driving range, and others never get off the 12 hole challenge courses with big cups. So what?
Well, tradition is great, and change is constant. While we all love golf as it is, it is not out of the question that it will be forced to change with the times to survive, even having done quite well for 500 years without a lot of change (although, we can all argue that, and often do when it comes to tech, turf and whatever else) For that matter, is the "golf is meant to be tough?" really true? Or was golf meant to be fun?
I think what the USGA gets stuck on is the "one rules" setup. However, its not like every course will have 15" (or pick a more reasonable size) but that some will offer an alternative. I see a lot of housing courses converting parts of golf to more residential for profit, but also horseshoes, dog parks, skateboard parks, whatever, leaving the 9-12 hole challenge course (or whatever the site dictates) as one recreation option, not the only one. We have so many more recreation options, it could be the "market" will tell developers.
More than that, just as modern courses got more visual because we were the TV generation, I fully expect some design changes for the next "play station" generation. Not sure what it may be, but will center on more tech and more "instant information" to reflect life as it is and will be. Probably more like Top Golf, with computer chips embedded in the ball for total shot link type info on every shot in the players Google Golf Glasses, or something like that.
Of course, none of us can say, but it may be that golf has a tough choice - remain an old world game that a few play in secret, and a few others try every few years on a lark, or get with the times. Most here will protest, but again, none of us can say if golf can stick its head in the sand and survive.
Or, with 15K golf courses, some blend of both. Now, you might be like the USGA guy who said Hack Golf can do whatever they want, but we won't call it golf. Fine, although I think keeping the loose affiliation with golf as the ancestor is probably inevitable (Top Golf.......I am your father......) Or not. Maybe the generations of minorities and poor that have a bad image of golf might be more likely to take it up in some other version called something totally different.
