Do first sale protections apply to physical things? I thought first sale was an intellectual property / copyright thing.

Yup. Most recently, see Impression Products, Inc v Lexmark where the Supreme Court held that the initial sale of cartridges exhausted lexmarks patent rights and thus couldn't prevent 3rd parties from refilling.

It absolutely applies to physical things. If I buy a widget you sell, I can do anything I want with it, including resell it.
