The existential bit there.
You'd initially think 'police, if you don't enforce my control over other people they'll kill me' is a bit hyperbolic. But I suppose in terms of a personal fiction only existing so long as no one speaks the truth, it may feel like that.
Unfortunately, however it feels, it is not justification for that coercive control over others, or preventing them speaking the truth, and expecting them to go on performing that lie for you obediently regardless of situation or consequences to themselves and others.
