In all likelihood, the reason they appear to talk the most sense to you is that both you don't understand what is wrong with them¹ and you never even read the actual theories they pose themselves against.

Anyway, the criticism about the Austrian school isn't even that it's wrong. It's that it's neither a theory nor a school of though. There isn't much "though" in it. But when you get to the views of an actual person, they will necessarily be more complete than the school, and need to be evaluated independently.

Fringe means that it attracts weirdos, demagogues etc, as things normally fringe for a reason, but even if they are not, people have so much reputational risk for publicly advertising these views, so that either suggests they are grifters, so they do not have reputation to start with or they have poor judgement.
