I've been involved in more than one purchasing decision where the ability to resell the parts was factored into the sticker price.
For second-hand CPUs? Not likely.
If it doesn't fulfill that need, even second hand, you can get your money back.
What you are suggesting is absurd. Craigslist, Ebay, Paypal, and the people selling using those platforms are above the law?
It sounds like you might not be familiar with any of the platforms in question. But no, you can't do either of those things to the kinds of people who deliberately sell defective parts on ebay and Craigslist. Or at least, you won't once you figure out what's actually involved.
I would say beside as opposed to above, but it sums to the same thing.
Are as-is used car sales illegal in that state?
