I'm saying artists and musicians aren't a bonus. A city without them might be functional, but no one would love it and few would call it thriving. No part of a city is really inessential.
My hometown wasn't really known for artists or artistry and I still loved it. I think the desire to be around art is one that only part (maybe even a small part) of the country shares. Having it is nice, but not having it isn't really missing out on much, and it's fairly low on the hierarchy of needs.
