I think it's only the HN crowd that tries to look at side-projects from the monetization angle. (How else do you explain the frequent 'what's your side-business' posts? Also, this is a VC's site after all.) There are many computing cultures - people making games for gamejams, working on quines, writing code for GameBoys, contributing to Firefox, Arduino hackers. Maybe finding one of those groups will change your mindset?
