I'm worried that players that are already used to selling stuff for x price will continue to sell it for x price. So if a miner is used to selling his product for 50k, he continues to sell it for 50k, he doesn't switch to selling it for 5k. So, all this accomplishes is the reduction of the amount of people who can buy the product and helps to further increase the difference between those who make a lot of money and those who can't (ie: crafters that already have a lot of money, and new crafters that can't access very expensive raw materials).
