I'm in favor of this change. I think making all aspects of this game equal opportunity is important and if there is no way for a new player to come in, buy cards, and then choose to undercut the existing market that isn't equal.
That said, this shouldn't have been a proposal. Just update the code and roll it out.
If we have to pay 100k DEC for every little change that needs to happen we are quickly going to rug the DAO.
