What if a blocked path is not a blocked objective?

The objective and the route are different things. A financing structure, counterparty, timing assumption or control constraint can fail without proving that every lawful, economically defensible path is closed.

Ask what would have to be true. Map alternatives. Test the evidence, dependencies, duty and economics. Set an explicit invalidation condition. A non-zero possibility is not a probability estimate, a guarantee or permission to take an irrational risk.

If the only remaining route fails law, economics, duty or factual reality, kill that route and redeploy.
