Yes, it is a problem because that would change our game more than this insignificant modification of the definition of what constitutes a stroke. Your examples are of TEAM sports in which the organized versions have a cadre of officials whose job it is to call fouls. You simply can't transplant that over onto a sport which is played solo with that task placed on the player. (Even when playing in a group, you are solo unless it's match play.) The individual player is responsible for his adherence or nonadherence to the rules. If you choose the latter, then have at it, but forget about playing in any authorized competition.
You still haven't come with anything persuasive to support your premise. I still say that your problem isn't with the change itself, but you just have a problem with anyone having the effrontery to try and tell you what you can and can't do.
I am not the one that started the well other sports have conformed rules, maybe you should read all post before commenting, your team examples. My premise, I stated that I that Mark King sounded right in response to someone calling him a Kook. I really don't need anything to stand on as that is MY opinion. Everything escalated from there, yes that was probally mostly me. I don't mind a good debate. And yes my problem is someone telling me what is best for the game, that's like the government telling me what's best to do with my money. Yet no one has said how banning an anchored putter will make the game better/funner.
The point isn't "funner". The point is refining the definition of what constitutes a golf stroke, and the history and tradition of the game says that anchoring to a pivot point isn't a proper stroke. Such prohibitions have been made several times in the past, so there is even a precedent for it. You aren't allowed to push or scoop the ball. You aren't allowed to putt croquet style. You can't get down and use the putter like a pool cue. Hopefully, soon the anchored putting stroke will join those other prohibitions.
