No it isn’t. Its no different than the different pro baseball leagues, that grew from one. The difference is in golf each player is one unit where in baseball each time is one unit.
Anyone could form a “competing” golf league and if it was formed to operate like the PGA, based on competition, not $zillions to players to just show up. that would be openly cometitive with the PGA. But such an idea is NOT what LIV is about, its 100% about the money, because buying what they cannot reproduce is all of what the Saudis know.
An anti-trust case against the PGA would be fun to watch.
.Gov would win in a slam dunk—they would be broken up into a hundred pieces.
Good luck defending them!
