Democracy works really well when everyone in the voting group respects and values each-others’ opinions. I think this is probably only achievable in quite small groups.
Once it gets too big when a decision that you don’t like comes down the pipeline it doesn’t much matter to you whether a dictator proclaimed it or a bunch of faceless strangers voted for it.
If you live in a population that is large and non-homogeneous and are part of a minority 1 person 1 vote doesn’t feel great.
