> But then it's like, should we protect people from anti-vaccine messages or other misinformation? Is the only way to prevent societal collapse to have a higher authority step in and protect people who cannot resist temptation from themselves?

Society is comprised of people, and some members of society are indeed vulnerable and susceptible to abuse. Society is expected to step up to stop and punish abuse directed at vulnerable members of society, like how the police intervenes in domestic violence cases, and how social services intervenes in at-risk families.

I don't see the point of arguing against protecting the most vulnerable members of society. There is zero to be gained with Spartan approaches to it's weakest and most vulnerable members.
