> In any democratic system the government exists with the consent of the majority of people.
This is incomplete to the point of being incorrect. The correct version is:
> In any democratic system the government exists with the consent of the majority of people who happen to have the time/energy/intelligence to research candidates and physically cast a vote in spite of various barriers to voting, choosing from among the small number of candidates who happen to be running.
Sure, but so long as the democracy is still technically functioning those laws can be changed with enough support. Most of the barriers in place, whether they should be there or not, are not insurmountable.
I guess I'm defining consent as "anything less than a desire for violent overthrow of the government" because that's the primary problem democracies solve. Things can still get bad to the point where in any other system a violent rebellion would take place, it's just that in a functioning democracy there's a bloodless rebellion at the ballot box instead of a civil war.
