We are (well, I am, and TFA is) not talking about epistemology so much as the public's inability to engage with epistemological problems on systemic scales. Instead the limits of human psychology control how we as a society respond to these issues. Your argument is a distraction that remains uncontextualized within the conversation it finds itself in.
People are not dumb animals but you won't be able to engage anyone toward a solution on the basis of an argument about how they just need to understand more about epistemology. That's the kind of thing that people can only internalize via empirical means.
At this point it feels like you're being deliberately obtuse. I've been quite clear about the primacy of human psychological limits as the main aspect of the argument and you simply refuse to engage with this point. You haven't been very good about adding to the conversation, only diverting it.
