To add to what you’re saying, the Weimar republic was not a really a democracy when Hitler got in power; it was already ruled by decree, with a reactionary minority (Hindenburg, Papen, Schleicher and al) aiming to ignore parliament and preserve the nobility.

In early 1933 a German observer might have hoped the authoritarian trend was just a temporary thing and the presidential clique would have to bend to the parliament eventually, since they were continually losing support.
