A libertarian society doesn't coddle you, but it still accepts that the state has monopoly of force, and it accepts that the state needs to be fair and predictable.

I think the author's fear would be that we currently live in an informational vortex that threatens to destabilize and consume our democracies and societies, and remove even the possibility of a fair and predictable state.

And I would argue that that is hardly an outlandish fear. It's barely an extrapolation at all.
