To give a glimpse of what people are missing by ignoring Hoppe just because someone else said he's not cool, here's an extract of a footnote from his essay titled 'In Defense of Extreme Rationalism':
"Though quite frequently mentioned as an empirical counterexample, it should be noted that quantum physics, or more precisely the indeterminacy or Heisenberg principle of quantum physics, correctly interpreted, is in accordance with this. What has been previously said does not preclude—and this is precisely the situation in quantum physics—that in order to experimentally produce a result, two or more measurement acts must be performed and that because any two separate actions can only be performed sequentially, the performance of the latter act of measurement might change the results of the former one, so that if this proves to be unavoidable, the results in question can only be predicted statistically and a deterministic explanation proves impossible. But even here each separate measurement act presupposes the validity of the constancy principle—otherwise, neither of them would have been performed; and the sequence of acts, too, presupposes constantly operating causes as it would otherwise be simply impossible to repeat two experiments in the field of quantum physics and state this to be the case. Moreover, the experience of quantum physics is in exact line with the preceding conclusion regarding the characteristic of causality as an action-produced phenomenon and as a necessary (known to be valid a priori) feature of reality. If causes can indeed only be measured and identified sequentially, by means of actions that have repercussions for each other, then they can, in principle, only be causes whose constant operation is of a probabilistic kind—and this, to be sure, can again be known to be true a priori. Quantum physics then only reveals that cases such as this are not merely conceivable, but do in fact exist. See on this F. Kambartel, Erfahrung und Struktur, pp. 138ff.; also P. Mittelstaedt, Philosophische Probleme der modernen Physik (Mannheim: Bibliographisches Institut, 1968)."
