>There is much more to it, like a free conversation in society, strong independent education, journalism, justice, protection of minorities, etc.

All in theory. Otherwise we wouldn't debate this. Historically none of these traits are unique to democracy, but developed society. US had a civil war over protection of minorities even though it was considered a democracy.

>In a democracy you have an independent judical system that you can use against government overreach.

Which can only follow laws passed by the government. Separation of powers is not unique to democracy. Again the coercion mechanisms doesn’t matter, but the severity of it.
