In 'unanimous' decisions, often the majority kicks out the minority who voted the wrong way until they get a unanimous decision. This happens in academia. Consensus is reached when we kick out the quacks.

In practice, in national politics, how could it ever be decided? Only 10% ever do anything. Naturally I subscribe to elite theory. People don't revolt. The elites rally the population to do what they want. Don't forget that Rosseau is writing to convince the people of his generation.
