>Only a few will make personal sacrifice for the common good.
Are you vegetarian? I chose to, only because I want mankind to live on this planet for a long time. That's not a sacrifice, that's a basic choice. I'm not sacrificing stuff when I chose to behave responsibly (e.g driving safely, not stealing my neighbors, paying taxes, etc). Do you think people only pay taxes because they fear the police? Or they don't kill each others only to avoid going to jail? Of course they are abuses on our systems (like any social situation), but if you think most people behave responsibly only to avoid a kind of punishment, then you have a very dark idea of society or you hang out with bad people (that can change).
Yeah, like the GP said.. only a few. And I think you have pretty rosy glasses if you think people pay taxes cause they care about their fellow human...
Try explaining this to BILLIONS of people across India and China who are now for the first time in their family's generations being able to afford and access a diversity of protein-based and vegetarian cuisine (available all the time, in and out of what they used to know as the season of availability).
The point is it will take a regulated solution or some sort of new product that creates a serious incentive to adjust mass behavior.
You are benevolent in these ways. Most people are not. If most people behaved the same way as you, tragedy of the commons and moral hazard would not be real things. But they are real things. A successful policy will take that into account, not just hope for everyone to be benevolent.
