I don't disagree with any of your statements. 

But let's go back to where it started. 
"Voting is immoral".

Like it or not, there will always be leaders in one form or another. 
Voting is one method for the group to decide that (allegedly).
A group that has voluntarily decided to use that method is not acting immorally. (In that moment)


Does it end well? Generally not.
Does it lead to humans gaming the system and appointing psychopaths?
<gestures to... Well... Everything>

Are you making the argument that because voting is immoral because it can (predictably) lead to the state entities we see today?
