The rules of golf have failed the game. If the rules are to complex for a human being that earns a living playing golf, needs another human being or a team of officials to assist with the most simple of rules, the rules fail the game.
For the weekend duffer would it not be better to have basic rules and play them correctly. The handful of basic rules we all need to know are not even understood and followed my the majority of golfers. Example hitting a ball out of bounds--100% understanding and following of the rules never........Yellow line vs red line--focus on the basics and improve the game.
A one page rule book would allow 99% of the golfers to understand the most important rules and how to follow them. Which would be a huge improvement over the current situation.
If the pro's can play "clean, lift and place" and not have the golf God's rolling in their graves they would surely approve one or two page rule book.
Who is going to decide what rules are "most important'? You are simply talking about playing procedures. What about the procedures to follow when those "most important" rules are broken? What do you do with the less important (in your mind) rules? Your game would be unrecognizable as as golf.
As Erik has asked - if you can come up with a one or two page rule book, then let us see it and test your theory. I think he set up a wiki and another thread for you to do just that.
