That many of the norms, values and practices that make up a traditional society are non-voluntary - in the sense that it doesn't make sense to speak of people assenting or not assenting to them - and therefore cannot be seen as constraints on human freedom at all

......even by the individuals affected? If they tell y8u that they hate being forced into a particular role, you're going to tell them that their feelings don't matter, because you can prove logically that it is non voluntary, and that you can't rebel against your identity?

There were, of course, bad monarchs, bad religious leaders, bad family circumstances, etc, but the liberal claim is that it was all bad, all the time (although it is apparently unnecessary that anyone noticed, since everyone was also ignorant).

It's worth noting both that the oppressed were often denied a voice, in the sense of leaving a written record, as part of their oppression....and that there is plenty of evidence of dissent , in the form of popular revolt.

It's also worth noting the difference between far left and classically liberal versions of this argument. (A perennial problem with Moldbug is the way he conflates progressivism qua the leftmost 10% of the spectrum with progressivism qua the leftmost 90%). The classical liberal does not regard traditional societies as morally wrong so much as instrumentally wrong, unsuited to economic and technological progress. Where you have a traditional, hierarchical society, the rulers of that society are under a set of incentives to defend their relative position, which is to say they are not incentivised to promote innovation. On the contrary, even technological developments can sunset them, as the English aristocracy was disrupted by the Industrial revolution.

Liberal democracies, by contrast, are so good at reaping the benefits of progress that, they are able attract queues of would be immigrants from more traditional societies.
