The question is - do you want MMs?
Or would you prefer a matched bargain system where you either put your stock up to be sold at a given price, or wait until a buyer is offering a price acceptable to you. (Or vice versa, of course.) Makes trading less of an instant affair!
The downside of MMs is they need to take their cut, hold stock, and publish trades according to a set of rules they say "makes for an orderly market".
