Please don’t post leading questions like this. It’s clear you don’t want the lockdown and subscribe to objectivism. Blanket philosophies always have edge cases and if you can’t accept that there’s no room for debate.

You can't just discard the necessity of cooperation in specific instances where the benefit you personally receive is lower than the amount of effort you need to put in.
