@Horton I actually understand where you're coming from, and agree with you - to an extent.
I get lakes having long cues to ski and everybody get equal time on the water. Unfortunately, it's not always as you have described it. Believe it or not, there are ski lakes that don't even offer rights to use the water to all of the surrounding (touching) lots. Primarily what I'm getting at is that there are lakes where the majority of lot owners don't ski, and sit on their memberships to prevent others from having the opportunity. They like having the calm water out back and don't appreciate outsiders (even those skiing as a guest of someone else) using the lake. I've also heard this mentality justified by claiming that the lake membership could be used as a selling point when they are ready to sell their home.
So if the lake isn't being used at all (or very little) because the members like their peace and quiet, then that leaves other ballers out to dry, and thus has a negative effect on the sport. I know of several lakes that either once were this way or are now.
That's where the community atmosphere is important to grow the sport. To tie this back into how it relates golf and skiing: think of it like a semi private golf course. There are days it is members only, and other days it is open to public (outsiders) use, but priority goes to members first. Allowing access, within reason, to guest ballers to use the lake for what it was built, should not seem absurd. Growing the sport is about being inclusive and doing away with the exclusive mentality.
