The difference is even casual non-crafters could get and sell sealant from doing extremely simple beastman dailiies. Many, many, many, many did. It's why the system worked at all. Unless red scrips are equally easy to get, you will not be seeing anyone but the top-end crafters getting them. And a top-end crafter will not be selling the mats you can buy with them, at least not for anything less than 10mil-50mil a piece. I know I wouldn't sell such a precious commodity for less.
