"You"? It seems you didn't understand my previous comment. Fine. I really don't know how to explain the concept much better. It's something about not putting absolute ideas over people, including oneself. That's not to say despising common interest, but just having a little common sense.
Let me share an old story of my hometown. Public water supply pipes are a disaster in the area. I saw an official report that showed that the waste was between 20% and 40%. So, even if this is the spanish province with the most rain, we suffered from restrictions most summers. No current water from 10 PM to 10 AM.
Now two infuriating (for me, at least) cases: one nearby village spent a hefty sum repairing the pipes, so no more leaks, and a family here that installed a reservoir in the roof to have water after 10 PM. Please notice that cutting the supply is not intended to make people consume less (they do more since water is kept in buckets for the night), but to reduce the leaks to half (half time pressurized pipes).
The family was fined because they were not "solidary" with their neighbours. The rest of councils of the area made a big noise and demanded the village that had invested in infrastructure, and thus attacked the root problem, to put restrictions in place.
You might think that these stories have nothing to do with the current conversation. Maybe I should have written about the fines for not recycling while there were not recycling facilities, so everything ended in the same dumpster, or the golf fields that sucked tons of water, I don't know.
My point is what I wrote above: beware of this kind of absolute idea when they stomp over people or common sense. Do what you reasonably can to make the world a little better, but don't put the responsability to save the world on your shoulders, that's not healthy.
