The "simple measures" you name are things that require political will, and America doesn't have it. That's why these things are infeasible: American voters have to want them, and have to elect people who will enact them. They're not going to do that, outside of a few select municipalities (where obesity probably isn't a big problem anyway, because the people there are wealthy and educated). Even worse, America is almost certainly going to elect Trump for a 2nd term; the country is swinging conservative, so these "simple measures" you name definitely aren't happening any time soon. Look at NYC for instance: the Democratic state governor just scrapped their congestion charge program, so living in blue states and electing Democrats isn't any kind of guarantee of positive change either.
Honestly most of the stuff I mentioned is pretty in line with Bidens infrastructure plan which did actually pass! But even if you say my proposal is pure political fantasy, so is giving everyone ozempic. If we’re actually going to dream of fantasy proposals, “give everyone drugs to mask one symptom of our many problems” seems to me an impoverished fantasy.
