One's first thought - okay, my first thought - is to take this as evidence that golfers are insane for putting up with this. Golf may be among the most individual of sports, but this sort of pettifogging nonsense is a libertarian's nightmare.
On the other hand, golfers don't seem to mind it, and even embrace the precision required. The sport does have fewer scandals compared to...well, anything, really, and that may not be accidental. When you look at it a certain way, professional sports are federalism in action. Each sport can have whatever rules it wants, and enforce them as strictly or loosely as it pleases. As many athletic attributes transfer from one sport to another, some athletes have a degree of choice what they want to put up with.
Freedom also includes the freedom to put up with excessive and unfair discipline.
