In aviation we have a thing called 'envelopes'. Weight and balance is one of those envelopes. Anything within the envelope is acceptable - and if that also translate to a price for being within that envelope then so be it.
Which then leads us to the inescapable conclusion - anything outside the envelope is not acceptable and, if associated with a price, then that price must reflect the deviation from the norm.
