@bright_helpings It also doesn't /not/ have a policy implication, framing it like that.
Ozempic is a medical intervention sought out (usually) by the one being affected by it, with the motivation either legitimately justifiable health concerns by medical professionals for that individual, social bias repackaged by medical professionals as health concerns for that individual, or raw social stigma against fatness that the individual is trying to avoid.

Oversized cars don't cause health impacts for their users, so this comparison implicitly suggests... what, a public-shame-based policy trying to socially punish people who buy oversized cars?
Which is impractical and a specifically bad match for this case in particular (consider car-buying cadence, for one), even if there is some sort of area where it might work.

I recognize the article almost certainly doesn't argue that but if your metaphor is pushing directly against your argument it's a sucky metaphor.
