You'd have to establish rules for what would need to be sold MSRP for Buy It Now - I would prefer companies NOT have that say, because there would be too many that would insist that it's also a floor for what the price can be, and might also impose rules as to who can sell their products (even marked as used in some cases), and it would need a specific time limit - either the product still needs to be produced/actively sold (so that it avoids earlier console generations being caught up in a company's desire for sales, although the current players may well not abuse it to ensure that people are discouraged from buying the last generation used), or not a specifically "limited edition" thing (it's hard to justify enforcement on something that's sold at $1500+ and only had a few hundred available compared to a normal edition).
Basically, you'd want to tailor it so that the scalpers are squarely in the sights of it, with no wiggle room for violating the intended spirit versus letter of it, while at the same time not providing ways to punish people who feel buyer's remorse or had a sudden incident and that "luxury" item suddenly needs to be sold for some sort of value.
Such a rule would need to work hand in hand with companies limiting the number of units sold to one account on sites where buying bots have been serious problems.
