I have a day job that pays the bills. Gigging for me is about the mental exercise and enjoyment of playing and a little bit of socialising. I happily admit I do expect to be paid enough for an evening's work in a pub and the travel to get there, but at the same time, I have cheerfully given up occasional afternoons or evenings to do things for free for Help The Heroes and such. The playing is sometimes enough for me.
Rehearsing should be to get new songs in, or to tidy existing ones up. Not a paid-for evening's socialising.
I would not gig regularly for nothing, as I believe that is what people who are out there to be discovered often have to do. I'm not out there to be discovered any longer. Good luck to those who are prepared to invest their time to get ahead, though. Horses for courses.
