It means that in order that the liberties of all may be preserved the liberties of everybody must be curtailed. When the policeman, say, at Piccadilly Circus steps into the middle of the road and puts out his hand, he is the symbol not of tyranny, but of liberty. You may not think so. You may, being in a hurry and seeing your motor-car pulled up by this insolence of office, feel that your liberty has been outraged. How dare this fellow interfere with your free use of the public highway? Then, if you are a reasonable person, you will reflect that if he did not, incidentally,* interfere with you he would interfere with no one, and the result would be that Piccadilly Circus would be a maelstrom that you would never cross at all. You have submitted to a curtailment of private liberty in order that you may enjoy a social order which makes your liberty a reality.*
Liberty is not a personal affair only, but a social contract. It is an accommodation of interests.

* ‘Incidentally’ in this case means that the policeman is stopping you to deal with some specific incident, not dictating every aspect of your joutney.
