In general, trading an artisan for a keyset is a bad deal for the guy w/ the artisan. Keyset $ value and artisan $ value can't be compared where there isn't an efficient market (partly having to do with the fact that people irrationally overvalue keysets and will reject trades for an artisan worth signficantly more than the keyset).
I don't agree that it's a bad value. It's not like tigersharkdude can go out and sell his reaper for profit and have enough to buy a hyperfuse set or he'll risk not being allowed to join any other of Bro's sales. If he has no use for the reaper than it's a perfectly good trade to get a whole keyset that he can put on a board.
Say Reaper is worth $250 and Hyperfuse is $200 (just example numbers). To avoid running afoul of the ban on selling above retail, he could hypothetically trade the Reaper for 5 caps that are worth $50 each by Artisan XYZ (a hypothetical artisan who has no restriction on aftermarket sales), sell those 4 of the 5 caps, and then buy Hyperfuse while still having a $50 cap by Artisan XYZ (as opposed to just having Hyperfuse).
--which, to be fair would be a stupid and time-consuming thing to do. My point is that in some ways, when you trade a reaper for hyperfuse, you are losing out on some value, even if you are not selling the reaper.
