Free contracts are a fiction.

Everyone has obligations that tend to reduce their freedom. The ones who think they don't are called psychopaths.

In personal development, an early stage is to understand that you can be independent. E.g. you can choose how to act and how to react to the outside world.

A higher level of development is to realize that we're inter-dependent. No man is an island.

There will always be constraints on our options. I don't like it, but I'm getting used to it.

There is no absolute freedom, and there are no truly free contracts.
