I'm on edge here. Are you going to give us the answer?
Answer to what?
Here's my take. In most things,
everything else being equal, low cost is better than high cost, and free is better than low cost.
That's a different formula than whether the item or activity is worth the cost. It may be. it may be a bargain at the cost.
It's also a different formula than whether the entity is entitled to charge. If it's entitled to charge and does so, that's fine, but not as good as if it's entitled to charge, but doesn't.
No difference for disc golf. If a disc golf course that charges a fee, has a "free weekend", that's a bonus. Correspondingly, if a free course then charges, that's not.
I can think of a private course that doesn't charge, but limits attendance. You need a reservation -- you can't just drive up anytime you want. It's part of the deal of the course being available, at all. Would I call that a "con"? Yes -- and I did, in my review. It's less convenient. But would I fault the owner? No -- I'm he.
Same with P2P. It's not as good as free. It might still be a great deal for the chance to play the course, it might be completely justified by the course owner, it might have benefits in course maintenance and crowd control that outweigh it's drawbacks. But in the realm of pros & cons, it's still a con.
