yes exactly. I think some cards should be priced in such a way to encourage players that need them to be able to afford them. I will list many that will be inexpensive I'm sure.
I do agree with you this is a win/win... In fact I think it will be a win/win/win ... players/renters/game ...
The reason is say the game is not only the burn for the economy, but also the much better user experience because card owners won't be yanking away the rentals every few days to get a few more bucks. Plus some aggressive card owners constantly tried to undercut each listing by trivial fractions that made rentals very frustrating.
