Who can leave?

The third boundary asks whether leaving remains a real possibility.

Many arrangements appear voluntary. A person may be free to leave in principle while being unable to leave in practice.

Formal exit is not enough.

A boundary is approached when exit remains legally available but becomes practically inaccessible — through dependency, debt, the absence of alternatives, or the way the arrangement itself is structured.

The presence of a theoretical exit does not establish the presence of a real one.

Freedom to leave means little when the cost of leaving exceeds what a person can bear.

The boundary is crossed when exit exists in form but not in fact.
