Imagine a society that had rules on the designs of haircuts, and punishments to enforce those rules.

Except people aren’t addicted to haircuts and presumably don’t spend 8 hours a day staring at their hair in the mirror.

I should be able to stare at my phone 8 hours a day without government interference if I want to. No one is holding me at gunpoint. It's my phone and it doesn't hurt anyone else.
