That's still an extremely opinionated viewpoint. Some people are happy to work a 9-to-5 gig because it affords them stability in exploring their other hobbies.
I agree with your sentiment and find the judgemental, derisive attitude that some entrepreneurial communities exhibit distressing. Going so far as to call 9-to-5 workers sheep is a display of arrogance and (perhaps) own insecurities. It would be better for us not to foster such attitudes.
This has been a big regret of mine. I should never have preceived anyone in a 9 to 5 that way. And as mentioned above, there is nothing wrong with a 9 to 5 (dice or no dice). It’s a prefectly valid course of action to pursue the more important things in life.
