Would love to hear some more about your realization. Any thoughts on what it is about either governments or sensible environmental laws that makes this the case?

edit: After rereading I realized I misinterpreted your post. I read "enact" to mean "enact and enforce" but in a sense you are correct that only governments can enact legislation. I see now you made no claims about ability to design enforceable policy.
