Perhaps “state” is more synonymous with “welfare state” in Sweden? (I’m speculating here…) Mises stated clearly his opposition to welfare-statism. While he clearly was not anti-State in the same sense that Rothbard, Hoppe and Rockwell are, he wrote approvingly of many of Rothbard’s works. And as noted above, taking a namesake for an Institute is not the same thing as adopting that namesake’s beliefs as a dogma - it simply means “we’re inspired by this fellow but (of course) we have our own views which may differ from his in certain details.”
