The Social Contract is an act of usurpation, a way for leaders to claim unearned legitimacy. Now, they even go further in pretending that the electoral system as it stands is your voice. Again, no freedom at all, here, and even less democracy. Anarchists are the only unequivocable supporters of direct democracy out there, folks. That's one of our greatest strengths, which is why we've locked horns with government for over a century.
Society can function that way, but forget liberty, freedom, justice, and equality.
Anarchy is the only way to achieve lasting, true democracy. It's up to you what you get. Everyone pretends it's democracy, but in fact it isn't. It's a sham. Anarchists alone call attention to this and seek to bring democracy into daily practice for each of us, so we can each live our lives as we see fit, so long as we respect one another's liberty.
