The Future of Ringing intersting article. Certainly there are positive aspects of the voluntary model, which may partly explain why it has persisted. But I don't think the example in the story is a very good analogy for teaching ringing. Jack already had the skill to play and was playing with the older man as an equal. I think that would equate more closely to ringing with Jack the ringer in quarter peals, where both parties benefit. That already happens a lot, and afia no one has suggested payment for it.
The question for ringing is how to get enough Jacks an Jill's to the point where they can take part on on an equal footing in collective ringing. That requires far more individual tuition to develop the core skills than it would for a game like pool. The practical problem is the limited number of teachers who are competent to impart the skills, are in the right places where they are needed, and have enough time to give away for the number of re ruins needed. The result is not enough quality teaching for enough people.
So how do you increase the supply of hours of competent tuition? First you motivate competent teachers with spare time to give it away. We already do that, but we need more. How do you persuade competent people who don't have time to give away because they are busy trying to make a living? What happens with other performance arts? Some people make part of their living by being paid for teaching. Oh, I forgot, ringers don't believe in that. So let's carry on doing the same as before and hope for a different outcome.
I don't suggest that charging is a panacea. It's not, because we are all locked into a different way of doing things, so it's hard for any individual to change. The entrepreneurs who could make it work will deploy their skills doing other things where there is a demand. Ruling it out seems a needless constraint to impose on ourselves.
