Current socialist policies do have the consent of the governed. While I have great contempt for them, legitimacy isn’t a function of sentiment.
"A man’s natural rights are his own, against the whole world; and any infringement of them is equally a crime, whether committed by one man, or by millions; whether committed by one man, calling himself a robber, (or any other name indicating his true character,) or by millions, calling themselves a government." — Lysander Spooner, No Treason: The Constitution of No Authority (1867)
"Those who sell their liberty for security are understandable, if pitiable, creatures. Those who sell the liberty of others for wealth, power, or even a moment’s respite, deserve only the end of a rope... America’s historic misfortune is that her people have seldom been equal to the ideals upon which their nation was established. "— L. Neil Smith, The American Zone (2001)
"Of liberty I would say that, in the whole plenitude of its extent, it is unobstructed action according to our will. But rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add 'within the limits of the law,' because law is often but the tyrant's will, and always so when it violates the right of an individual." --Thomas Jefferson
