No, it's not a question of being a price worth paying. No one here is suggesting or condoning violence.
What's being pointed out is that there's an observable sequence of events in history which leads not just to violence but often to actual war when votes and elections are over ruled.
That's why Churchill said "democracy is the worst system in the world except for all the rest" , and " jaw jaw is better than war war".

Previous generations were well aware of the potential consequences of ignoring the electorate, which is why everyone was careful to preserve democracy.
