A frequent side topic on many threads covers "real musicians" - you have to gig five nights a week to consider yourself a real musician. And then the - if you don't play originals, you're just playing someone else's music, might as well be a juke box -vs- play covers - it's what the crowd wants to hear. Then the classic - if you have expensive basses, you're a bedroom hack, it's all in the fingers.
Why do we care so much about what everyone else is doing? We're all bassists and just the fact that we chose bass means that we're largely taking a backseat to the rest of the band. Copyrights are determined by lyrics, chord progressions and melodies. Screw the bass line. If we really wanted to be successful musicians, we'd work on vocal skills and play an acoustic fronting a band. So, maybe it's pent up frustration about nobody really caring about what the bass does until we screw up - then people notice.
If you just enjoy playing at home - that's great! You're still playing bass! If you play originals - awesome! If you're into covers or a tribute - rock it strong! Play a Squier - kudos! Play a MTD - great! Only a very few are actually going to make a living at this. Getting home at 2:30AM for $75-100 gets old quickly for some.
If you are playing bass and find enjoyment in what you do, you're doing it right.
