Let me offer a really quick point about the first one. It's not what happens but who does it. If the state begins to do certain activities, you will create some precedents that you may not want to see adopted more widely. We are heavy traders of commodities around the world, and right now we determine our own market interests. But the moment you ask what other markets would like us to do, you're in real trouble. Do we want our forestry policy to be determined by European forest practices? Do we want our fisheries policies determined by European fishery practices? That's the issue. If the market does it, that's one thing. If the state does it, that's another.
On your question about liability, yes, there is a liability redress regime that's implicit and quite explicit in the market structures in North America and around the world. When there are damages that are measurable and identifiable, there are legal processes for dealing with them. The markets and the law courts are actually getting along and doing that.
