I think too many of us think gigging is the only option - that playing for fun is somehow "amateur".
The best group of musicians I've ever been with is my jazz group. Amazing players, including a Berklee grad, who probably still plays 3 hours a day, just to improve. Other than "dinner music", it's almost impossible here to book jazz. So once a week we gather, have a beer or wine, and play the exact music we want to play, the exact way we want. Sometimes we have someone great sit in (like Roger Ball, from the Average White Band). A couple of times a year, a gig falls into our laps, and we take it. I gig I another band (rock).
Nothing wrong with that. We should play music because we like playing music.
