The scenario that is commonly used in these cases is a merchant that
provides a signed invoice "if you pay me X with payment_hash Y I will
deliver Z". Now the user performs the payment, learns the payment_key
matching the payment_hash, but the merchant refuses to deliver, claiming
it didn't get the payment. Now the user can go to a court, present the
invoice signed by the merchant, and the proof-of-payment, and force the
merchant to honor its commitment.
