Erik,
I agree with your comment in principle...but...PGA Tour players still have by-laws they must adhere too in terms of what they can wear, minimum # of events, interaction with other players and media, etc.
I do think its a valid criticism of the PGATour that they benefit of having players be independent contractors and avoid paying out on travel expenses, costs, health care, training costs, etc,....and yet still able to implement aforementioned rules and regulations to govern them.
Seems long overdue that anyone who shows up to an event and misses the cut should get enough to at least cover costs of traveling, lodging, caddy costs, etc. and I'd bet the PIP money alone would be enough to cover most of this.
