That may be true. But in my opinion, there are some things that we should be responsible for ourselves.
I admit that I'm a little crazy. But I will not wholly rely on my fellow man to provide me with clean water or food. And I will not, even in part, rely on my fellow man to deal with my bodily waste. Which is in fact not waste, but rather nutrient rich material that I feel is my responsibility to return to the soil from whence it came.
But that's just me.
