Awesome.
Regarding the argument:
I'd like to eat ice-cream for a living, but unfortunately there are lots of people who would do it for free.
If I think playing bass is so fun that I'll gladly do it for free, I should be able to do that without feeling that I'm stealing from someone. If a better bassists wants to get paid, they'll just have to find a gig that requires someone of their caliber instead of a mediocre bassist who will do it for free.
