It is a very important right to be able to bind yourself via contract. In exactly the same way as is the _right_ of getting sued. Tom Schelling wrote about these issues in e.g. The Strategy of Conflict.

The right to commit yourself is important, because it will make other people more likely to commit themselves to you.
