I'm only learning about the history of economics myself. It seems a lot of people interpret Adam Smith as advocating against any government intervention, even in the case of price-fixing. For example: https://www.adamsmith.org/blog/regulation-industry/misreadin...
I'm not convinced that it's deliberate. You can draw a parallel with free speech: is it about letting anyone say whatever they want, however loudly, as much as they want? Or is it about ensuring that everyone has a voice, i.e. preventing the loud people from drowning out or otherwise intimidating the quiet ones. You could well argue for the latter, but many people in the West assume it means the former.
