That comparison makes zero sense.

The police are a way for us to delegate our self-defense to a third party, the state. We give the police a certain level of authority in return for (hopefully) safety.

In your metaphor you're suggesting, "don't protect yourself, you already delegated that responsibility".

Censoring speech on the internet is exactly the same delegation of responsibility. "Don't protect yourself, delegate that responsibility to the censors".

Your metaphor is making the opposite point that you're intending.
