I don't get the message of your first three paragraphs.
Aside from that ..
> ... system of individual ownership of fixed resources (land, crypto, etc.) then the few there first owns everything, and hence, feudalism.
I doubt your claim here. Maybe there's some empirical evidence that these systems of individual ownership of fixed resources tend to lead to few individuals owning most of or "everthing", thus feudalism.
But for one, we do have very high concentration of wealth in the current fiat system. (So the alternative to the system of individual ownership of fixed resources apparently does not appear to have a clearly better outcome.) And two, this possibly existing empirical evidence may just reflect what happened until now, but the world is changing and new circumstances may very well lead to new outcomes.
> I dont take this sort of "moral economics" seriously ..
I don't follow, where you take the "moral" keyword from. To me, Austrian Economics is just a (heterodox) take on economic questions that differs in some key views from the majority of the economics field and what they are currently teaching, publishing, giving advice to governments about or implementing as economic/monetary policy.
> Its an attempt to deduce utopia from naive ridigid principles.
Fair enough, if that's your perception of what AE is, it's totally valid. Such vague counter position (that doesn't address concrete claims) is hardly valuable as an actual critique, though.
