But the market in skip[s is a decent analogy. Years ago companies dumped their rubbish in the river or the bush, that became illegal then they had to hire skips, then tips became more regulated as the effect of different kinds of toxic rubbish became apparent. Skips became dearer, companies become mopper and more smarter or efficient with their wast, and skip companies do the same in a cut throat competitive highly regulated market. A good study in a regulated and evolving market as new knowledge and societies expectations change.
None of this supports the proposed trading system over taxing the inputs though.
