"AFAIK, consumer protections are much worse in the US, so if anything it would be the opposite."
Claiming you're selling a new product and then selling a used product is straight-up fraud. This isn't even a warrantee issue, and no, the US legal system wouldn't just shrug and go "Oh well". This is the sort of thing that penetrates any amount of verbiage in a EULA the company may throw at you, including any sort of demand to go through arbitration, and depending on how widespread this is could easily become class-action, which is the corporate nightmare the forced-arbitration clauses are trying to avoid. You can't write yourself an open-ended right to commit basic fraud into any contract, no, not even in the US.
