Yes, and that's exactly what Stallman advocates. E.g., he criticized another license for requiring that each derived work must be distributed or published.
If you write something for your own use, there should be no obligations. But as soon as you give the work to someone else, every use of your power affects others' freedoms as well, so any arguments based on "absolute freedom" fail at this point, and you have to weigh the freedoms of both parties against each other.
