Free markets avoid a whole world of hurt. The invisible fist of freedom does it for us. When you can't coerce people into buying your product, or selling you theirs, many bad outcomes simply never happen.
Isn't it great having a big invisible buddy on your side? Unfortunately, he's easily offended by well-meaning acts of coercion. If you're not careful, he can invisibly slip away and you won't realize he's gone until you need him. Just a cautionary note. Don't assume that free markets will protect you if you've allowed them to become state-controlled markets.
