If you take these numbers for OHSAA fastpitch softball, in aproximation....800 teams @ 20-25 girls per team, that is around 16,000-20,000 girls participating in HS softball every year. I would say that only a 1/3 of those participate in travel ball. That would be 5000-6500 girls that participate in travel ball at the HS level, leaving 11,000-13,500 that do not play travel ball.
For these 11,000-15,000 girls, travel ball and specialty coaches are not an option, or they are unaware that they exist. This is where open gyms become beneficial, and a neccessity for the majority of high schools.
The notion that these girls are going to practice on there own, and then show up and play makes for a good fairy tale book, but not a reality of HS sports in general.
Another thing, there is a higher demand for quality paid instuction, than there are instructors. Its hard for travel players to get into a quality instructor, how do we get the 11,000-15,000, non-travel players this instruction?
