Public policy discussions that start with the assumption that the only possible solution is for the federal/state/county/local government to dictate policies from above are almost always non-starters for me. The higher up in the hierarchy the more evidence I need to support a solution at that level.

I'm not absolutist on this matter, there are concerns that are best addressed at all those various levels but I prefer to get there through bottom-up policy experimentation and iteration rather than top-down diktats. There are also ample lessons from history about the dangers of expansive government powers.
