Chapter 12 ties free sex and radical individualism together by saying they arise from the same false idea: that the self is the owner of itself in a complete and final way.
In the chapter’s logic, sexual disorder is not a separate issue from social atomization. Both grow from denying that human beings are ordered toward covenant, mutual belonging, and the good of others.
This gives the critique more explanatory power. It suggests that modern loneliness and sexual chaos are not random parallel crises but related symptoms of the same anthropology.
