Governments businesses need this information vitally, Rachel. Everything you have said here is totally correct. The problem is that you equate information with pricing. Representing complex systems with one number which we then use to make decisions is exactly the type of thing we need to try to avoid, no? And, once valued and presumably placed on countries' balance sheets as assets, will these various pieces of Nature be open to sale by government, or derivatives trading, etc? This needs to be addressed.
