It's worth remembering that the commons isn't well defined either. Lots of people view the current policy proposals of environmentalism as anti-poor and handouts to the third world. Whether you agree with that framing or not, there is plenty of data that shows mitigation and not outright prevention is an equally valid strategy to climate change. What you're really saying is that it's okay this time because it's an issue you agree with, a more neutral framing would be "...it's nice that they use it to avoid financing things we consider bad."
