It's absolutely insane.
If I buy a gun in the US it's quite possible I will never use it on public lands, wildlife are a public resource, so yes it will have a public impact if I use it to hunt, but I'm also buying a license to use it in that manner.
Conversely, I've never been on a private MT biking trail... does one even exist? Similarly skis... maybe some ski areas in the East? These are durable hard goods that are entirely dependent on public lands. Same argument can be made for backpacks, tents, etc.
If we went to a Texas model, all of these companies would just fold.
I know of bike trails that have easements on private and sure maybe some short track or something but I’ve never heard of someone with a 20k acre ranch building a 15 mile bike trail and then charging people to use it. Point being they are public trails, I don’t know of a private pay to use trail system.
Both Big Sky and the Yellowstone club are on private, a lot of ski areas have some of their buildings and infrastructure on private.
