For the same reasons we want tobacco regulated, alcohol regulated, some food regulated, and drugs regulated. The fact is that it isn't parsley, nor does it have similar effect on our body. While consuming too much might not kill you, getting to work and finding that your supposedly non-high-bringing cannabis-based pain reliever certainly made you high isn't the sort of thing one wants to find. Alternatively for recreational use, I want what the thing says on the package and would be horribly angry if I wound up with the other dude's non-high-bringing smoke. I want my "weaker" strain to be just that, just like I'd not appreciate finding out my beer/wine/whiskey is stronger than is on the package.
