I began playing guitar because I wanted to play and create music. It was rewarding on so many levels. I never wanted to play professionally and that was not my goal. Regardless, for about 12 years or more that is all I did every night every week. I made enough to support a family and buy new gear, and I did not miss any meals. I also burned out and was tired of playing covers that I didn't like, for drunks that I didn't particularly care for, and playing in places where I didn't care to play. I had offers to play in Nashville and in Vegas, with other bands. I chose not to trade my freedom for the total commitment I thought that would bring.
That didn't make me any less a musician. So what's the deal if someone says they play for the fun of it, and then tell you what they would have to have to play a job? A good many musicians that play for the sheer enjoyment of it, but do not like the feeling of being a bug under glass when they're on a bandstand, tell you what it would take to get them onto one? I can still play as well as most around here and I have severe arthritis in both hands. Septic, Rheumatoid, and Ostio arthritis + several others. It seems that is what my daddy left me in the gene pool. It would take a pretty big paycheck to tempt me to play a gig knowing how my hands would feel the next week or so. I can say I play for fun, but I would charge "X $$$ " to play a gig. So what is wrong with that? It's MY personal choice. If anyone doesn't like my choices, that is their problem, not mine.
Whenever someone decides that your personal choices need to fit their agenda, that pretty well fits the description of being a busybody. When will folks realize that personal choice is just that? It means you don't have to fit into the mold that someone else decides is right for everyone. They can say they play for the enjoyment of playing, and then they can also say how much they would charge to leave their personal choice behind, if their personal choice is to only play for the enjoyment of playing.
Like any other job, if you want to turn music into a job, you look at the good and the bad of the person you wish to hire. After all, there is a thing such as "Sorry, I don't think this is working out for us." How many musicians do you have to go through to get the perfect band? Sometimes it's quite a few, and even than it won't be perfect. If someone does find their PERFECT musicians for a band, why would they want to play for you in the first place? (Not specifically referring to you... just a twist in the old adage "I wouldn't want to be a member in any club with people who would let me join".
Jimmy had a good answer, so did Black and Bob.
