> We're concerned with society's safety, not just that of the user.

Preventing censorship is important to keeping society safe from authoritarians who want to influence public opinion.

> We deliberately shape the information environment all the time for different reasons. It can be done.

That's why we need to put in the work to inhibit people from doing that.

> But the media generally does not report suicides because of the copycat effect.

Yet they consistently fail to follow the same logic with respect to things like school shootings, implying that whoever is at the helm can't be trusted to make sound decisions, and then we certainly don't want anyone like that having the power to censor.

> Governments implement elaborate systems to guard sensitive national security information including the workings of certain advanced technologies.

These systems are notorious for over-classifying information that it would be in the public interest to release or being used to cover up misconduct.

> Criminal records can be expunged.

That means the government stops officially claiming you're a criminal and stops caring about it for a certain set of purposes. It doesn't mean nobody can tell you what happened.

> The sharing of health and education records are restricted.

Those rules are generally about securing information that neither the patient nor the medical provider have any desire to make public. Notice that if the medical provider actually wants to publish them they can often put it in the agreement as a condition of accepting their services and the patient can pretty much publish them whenever they want.
