What interventions could you not justify using this logic?

What a strange question. The interventions which would be unjustified are too numerous to list.

That's the notion of "false consciousness" that Marxists trot out to justify why they're right even though people don't agree with them. It's a tool for academics to justify imposing themselves as right-thinking elites who know better than the unwashed masses.

I disagree strongly with any authoritarian rule, but it is probably correct that the masses don’t actually know the best way to run society. That doesn’t mean we need to impose rule, it means we need to understand manufacturing consent (which is a distinct concept from false consciousness and well supported by the facts), it means we need to combat manufactured consent and better educate people.
