I used to hold an opinion of hippies similar to yours. Then 1. I watched the documentary on Woodstock and saw the disaster they made out of that place and 2. Spent a lot of time around my cousin and her friends when she was in art school. My conclusion was that hippies aren't any better or worse than other people. They suffer the same flaws as everyone else. The downside is that they seem to put forward this air of high-mindedness that rings pretty false to me.

And they have worse hygiene :)
