The Great Journey quest bug

You go down the cliff to open the chest. Then it removes your only means to get back out and leave.
So your only means of escape is to triport out of there.
I know it’s highly unlikely but imagine if someone had 0 silver with which to triport. What then? Are they stuck permanently forever? How else would you possibly leave that area?
If that was the case the player would be forced to use song of return or song of escape. The problem with that is those songs are disabled for that area. I tried and it gave me a message saying I couldn’t.
