One of the problems that I face at times when moving to a new house is what to do with excess bags. As anybody who has moved much knows, you've got to carry all the bags along on the move. It would be very convenient if there was a way to 'liquidate' excess bags. As it stands they can't be placed up for auction or sold to a Vendor. They can, of course, be given away or abandoned.
But are bags truly forever? Right now there is no 'exit mechanism' for bags to leave Ur. Once they are in the world, purchased from a Hardware Vendor, they exist permanently for ever more. I could see this as eventually becoming a problem, if people buy and discard a lot of bags. Personally I wouldn't mind being able to donate them to a shrine, even for zero or a very small amount of favor credit, just to get rid of them.
I know, I know. Fill them with stuff and give them to new players. Will there always be an ever-increasing number of new players to give them to? Eventually Ur will be saturated with bags. It could even become a griefing problem. Elemental Pouches are bags, too, and they're very inexpensive. Right now I myself could purchase 6,761 of them and litter the streets. Griefers could do so as well, and... there's no mechanism to dispose of them once they are in the world.
