I held this opinion too until I realized the extent of government surveillance. All that you said is fine until you add in that element. Ubiquitous surveillance by a controlling authority changes everything, because we are all massed together by their dragnet, against our will. In prison, not every prisoner comes into contact with every other prisoner, but they are grouped together by the controlling authority which watches them all. That is the analogy I presented. Increase the size of the prison and you have the appearance of freedom, but the elements of it still correspond one-for-one.
