While I agree that it is not a wanted change, I must wonder whether in fact new players would be used for it. After all, large sums of gold would be involved. Surely wise people would use nobles that could be trusted?
Either way it would destroy the part of the balance currently served by needing to return to a city to cash bonds. It isn't really important who serves as the gold carriers, though the risk of giving new players something that boring to to exists.
