Please name an arcane rule of that you speak.
If I am playing only with friends, and not in a tournament run by any organized body, association, or club, and I mark my ball on the putting green and then put it in my pocket; I am not concerned that I may accidentally pull a different ball out of my pocket. I would never do this in an actual tournament, but in a game with friends I have no problem doing this as there is no intent to just have a "putting ball" and I would have no problems with posting that score. (Although I never post scores and have never had a USGA handicap.)
When I used to play at Normandie Golf Course in my youth, the group of friends I played with had a standing rule - improve the lie, but not the swing, stance, or flight. I believe playing on a very beat-up public golf course we actually played a more authentic version of golf then some professional tournaments where 1/2 the course is GUR or played as "lift, clean, and place."
I play very close to the rules of golf, but there are certain rules necessary only for tournament golf that are required to verify no one tries to unfairly take advantage of a situation. The people with whom I play my regular golf, if they "respect" the rules, I am not concerned about certain rule violations that do not result in unfair advantage.
I respect the rule that one can not give club advice before a shot, but I have no issue with discussing advice "after the shot". But I also have no difficulty complying with that rule during tournament play.
The other perfect example is the "distance penalty" for OBs and lost balls. I would be furious if the group in front of me at a crowded muni came back to the tee box to re-hit. I will always try to hit a provisional (and I do declare that I am hitting a provisional, and I only use it for an OB or a lost ball and never for an unplayable), but if myself or a playing companion are at Forest Park and the ball is lost, we will drop as near as possible to where the ball was lost and apply two penalty strokes.
These items are the equivalent of going 4 miles over the speed limit. And this is from a person who will not even keep $1.00 incorrect change, or even knowingly $0.25 incorrect change, even if I am at a fast food restaurant or the most overpriced ball park.
