Why should I have to go through the entire process just to see the price? Have you ever been in a store that has the tax added onto the price tag? It is very nice to not have to do mental math.
I think this is the crux of our disagreement. In my experience, the more degrees of freedom the seller has, the more chances to fuck you over they have.
I think - and this might be my European perspective and maybe why we feel differently about regulations than Americans - the main source of risk is corporations trying to take advantage of you, not the government. Curbing said risk through regulations is a core part of good governance.

And there are a huge number of subjective judgements about what the worth of individual categories is, especially given the political nature of quality. Picking on one of my favourites - the US scores low on "Income Inequality". Income inequality is a weird measure because we'd expect the poorest people in society to have literally nothing (because some people are beyond help). Therefore the wealthier a society is and the more income inequality I'd expect as a baseline. People get worked up about it even though in practice it is a struggle to articulate how it is even a good or bad thing.
I'd invite you to sit out at a cafe in Florence, or on a terrace in Amsterdam, watching the boats go by.
I'd then invite you to take a walk through the Tenderloin of SF, global hub of tech capital.
I've done both. I've lived both. I can tell you that as far as my subjectivity is concerned, there is a clear winner, numbers on a bank account be damned.
One more note: A society in which the poorest are seen as a "beyond help" and left with literally nothing is not a society I would feel comfortable living in. It is precisely those folks that need the most help to make society livable.
And all of these are definitely worse than just making the vendor behave properly...
