Domesticity

In part I of 'What's wrong with the world', Chesterton poses the old 'principle of domesticity' as a basis. The family, in a home of its own, is in a sense beyond the laws of the state. The common man has, in his own house, a freedom he has nowhere else: a freedom to eat what he likes, to see the persons he likes, to paint his living room green if he likes.
Chesterton realizes that not everyone sees the home this way, but he is careful to explain to us that there is a difference between the common man and some great capitalists. Chesterton talks about limited property, and about working people who do not have time to be bored of their own home and family.
A marriage is a tie, a restriction, and this has been a tradition in most cultures. Chesterton finds it immensely important that one cannot severe this tie the minute it becomes uncomfortable.

In everything on this earth that is worth doing, there is a stage when no one would do it, except for necessity or honor. It is then that the Institution upholds a man and helps him to the firmer ground ahead. [-] Two people must be tied together in order to do themselves justice; for twenty minutes at a dance, or for twenty years in a marriage. In both cases the point is, that if a man is bored in the first five minutes he must go on and force himself to be happy. Coercion is a kind of encouragement; and anarchy (or what some call liberty) is essentially oppressive, because it is essentially discouraging.
