When hand-picking examples it's easy to use situations where the line is clear to the vast majority. However, I think we'd all agree that in everyday life there are an extreme number of situations where people would debate where that line should be drawn. Again, who gets to decide? The richest, the loudest, the majority (even if only slight), or who?
Still say I'd prefer it left in the hands of the people for as many things as possible instead of involving the Government. Maybe they'd actually take time to address the overcrowding at borders, the broken health care system or the education inequities if they weren't spending so much time determining what people and businesses should or shouldn't be allowed to do.
