I've been playing bass off and on for 18 years now and have always played either in a punk band or praise and worship groups through the church. In the P&W bands, I generally played with fingers and in the early days I used heavy picks but I kept throwing them on stage. I saw a bass player using the Jim Dunlop thumb picks and thought I would give those a try and I've stuck with them ever since. I've noticed I'm less likely to toss one and in all my years I've only ever had one break during a song. My fingers are still completely available if I need them during a slower, quieter part of a song (even though admittedly I don't usually go that route for punk). But, does anyone else play bass with a thumb pick? They certainly are harder to lose on stage, that's for sure. I've honestly never seen anyone else do it but in my opinion/experiences, it does make sense.
