If you dont pay a performer why should you collect money for people to listen..why come just to listen why not come to learn?

I pay to hear a performance because I choose to, because I want to hear that performer. I go to a performance to enjoy myself. I might come away wishing to learn a song I have heard, but that is a secondary matter. If I want to go to learn, I go to a workshop not a performance.

You can start by rediscovery of your local songs. Then listen and learn then adapt and write more....easy

Our local songs don't need rediscovering. There are plenty of people singing them already. Then, tell me how many songs you have written if you think it's so easy. I do not write songs as I find it very difficult, though I do write tunes.

Performers as professionals create scarcity by setting themselves apart. Scarcity causes prices to rise rising prices creates a barrier and not as many people have access.

Once again: complete bollocks. Some performers in other genres might be very expensive, but folk performers are not, on the whole. Yes scarcity might cause prices to rise, but if they rise too much, then nobody will go to the performances so the performer will earn nothing, so at the end of the day it's a matter of what people are prepared to pay.

If there were more demand from an expanded pool of players for expensive instruments their price would come down.

In theory that's correct, but the instrument maker has to cover his costs and good quality instruments need good quality materials and are partially or completely hand made which takes time so there will be a limit to how much the price can come down if the instrument maker is to earn a living.

Your last post is like so many of your others. You have latched on to an idea, but have not thought it through and have only a half-baked idea of the underlying principles. I am an engineer, not an economist but I do have some idea of the principles of supply and demand and it is clear to me that you have not fully understood them or, possibly selected those bits that suit your ideas even if the principles are inappropriately incorrectly applied.
