@Ilivetoski I don't think the affordability of skiing is destroyed by the lack of recognized public water "ski" zones.
Regardless of gear costs, boat costs, gas costs - all of which are scalable to talent level, participants, and region. Water access is, and will continue to be the singe largest cost associated with skiing.
My experience has been that the accessible water is unsafe due to high traffic, and so heavily boated that progressing with waterski skills is difficult - impossible. Less accessible waters increase costs and minimize access.
The public lake I ski with my family for instance has one permitted course, the owners of which I am friendly with. But it happens to reside in an area of of the lake that is close to a public ramp, and draws countless jetskis who buzz around the ball. No state protections exist for users of courses, or waterskiing in general beyond basic "right of way" type boaters safety rules.
For 800$ you can set up a couple used decent slalom skis with wileys and RTP's and teach almost anyone to round some balls, on that same set up many people will learn and progress, and eventually they will buy skis. A 100$ trip to the gas station gets enough fuel for a group of people to ski several sets, and ~10K gets a usable 19' ski boat with a perfect pass in it usable for pulling people through a course.
But when the course has someone anchored between 1 and 3 ball sunbathing, and they won't vacate, you have the MOST cost prohibitive portion of waterskiing - access to private water. That's where 50-100$ a pull starts to show up. At which point I am not skiing. 1200+ on a ski, sure, 400$ of bindings whatever, some 6 gallon gas cans I can handle, and I can pony up money for a boat. But buying a private lake and maintaining it is another game all together.
