Sounds like a case of "no true Scotsman" to me.
A *functional* democratic government requires more than elections, absolutely. However, in the context of democracy vs authoritarianism, the fundamental difference lies in how the people choose their leaders.
There's no need to choose any leader in a democracy. The only requirement is for people to decide upon something together with each one according to theory having an equal voice.
The whole leader issue is fog that clouds the vision on essentials. A democracy can have a lottery for leadership positions.
Democracies can choose to have an authoritarian dictator, authoritarianism is usually perceived as a system of lesser dependence on population goodwill. We might be better off with a different organization of the ideas shaping our discussion:
popular consent: dependent | independent
institutionalized | democracy? | 士大夫 Chinese scholar-gentlemen
personalized | Hitler,
| authoritarianism?
Is everybody's influence and voice equal in a democracy - lobbyism, campaign donations for spin doctoring?
Are authoritarian dictators really independent from popular consent - visible propaganda investments?
The Enabling Act of 1933 is something very controversial in the Western democratic cultures. The latest STAR WARS episodes 1-3 were about an enabling act for Palpatine while the old episodes 4-6 are a black and white world after that enabling act.
Obama's resonant campaign "Yes, we can." was as well about enabling one man to dominate and lead to a better future. Many see his failure due to the other institutions making progress an ineffective crawl. As long as democracy with her institutions exists, there will be a drive for empowered person to achieve more. You can similarly see the emperor and the scholar-gentlemen as a person of great power and an institution that both also rely on a degree of popular consent. The drive is always to do away with institutions and have one trusted man achieving sweeping changes. Winning a civil war is also a way to garner support because winning under such conditions is foremost about intelligence supremacy due to public approval (that can detoriate while still not overthrowing or inhibiting the winning side)
Btw. in Europe a high ranking scholar was equal in status to the hereditary military nobility.
There are many hybrids reflecting different approaches to theory and reality of "democracy" and "authoritarianism".
The
is an important base for the development of parliaments in most modern Western democratic cultures (including all Germanic and Romance language speaking countries due to all lof them having had sometime Germanic overlords shaping their development). It was an unequal assembly of males with military function(somewhere in between all adults or a fraction of the male population) that decided upon issues.
The other geographic half of Europe was under Slavic influence with the
operating as a similar military based concept with different options of choice.
They all share the Western and Central Eurasian idea that armies vote and which ruler would deny his armed forces the right to vote?
