They are voluntarily accepted limitations. The man with a strong sense of self-worth and independence, the man who loves freedom, will be cautious about accepting such limitations, and he will want to keep them to a minimum. He will be eternally vigilant to prevent other men from changing the terms of his social contract in such a way as to diminish his freedom. Weaker, more dependent men, on the other hand, may gladly accept more limitations in return for the promise of more social benefits or more security. And that's all right, so long as we don't let their weakness encroach on our freedom.
Liberals have an entirely different concept of freedom.
For the liberal the idea of freedom is mixed up with the ideas of happiness and comfort. To liberals, a hungry man is not a free man. And of course, in a certain sense of the word that is true. A hungry man is encouraged by the pain in his belly to do something to get food. Whether a man is hungry or not, whether he is poor or not, he is free as long as he not prevented by the government from seeking food for himself or seeking to alleviate his poverty.
