> Legislatures have tried to pass laws regulating commercial speech in various ways and the track record is generally that they get their asses handed to them by the court,

I mean, no, legislatures (both Congress and the states) successfully limit commercial speech all the time, which is, for instance, why no one in Gen X has seen or heard a TV or radio ad for cigarettes in the US when they were old enough to purchase them.

Broadly banning "advertising" (under almost any plausible definition that would be reasonably accord with common use) would probably fall afoul off the 1st Amendment as it is today, but our Constitutional system of government includes provision for changing any feature of the Constitution (nominally, except the equal representation of states in the Senate, but that restriction neither protects itself from being amended out, nor protects all the functions of the Senate from being amended out and the equal representation being at zero seats per state, so it is more of a symbolical than substantive restriction.)
