It's the same thing I've been trying to articulate about the gay rights/liberation battle. It's better in the long run to say, "Don't fucking tell us what we can and can't do if we're not hurting anyone," than to say, "We promise we'll be good," because eventually, with the latter, they'll hold you to it, and then it's too late to go back and insist on the former.
I bet there are a lot of hippies in lab coats at their "dispensaries" reading Wired and freaking out.
