Entry/Exit from Market
I suggest we drop "...at no expense." from the bullet on entry/exit from market, to something that means more in the way of "barriers to entry." For example: "Producers can enter and exit the market freely."

As it stands, it comes across as a little misleading. --Greenm1981 (talk) 20:51, 31 October 2008 (UTC)
