Are hardware IDs reliable at all - I've seen so many companies using HWIDs in their anti-cheats over the years and it has never worked; so I wonder if this would easily be worked around.
This is a different threat model than anti-cheat. Here you just want it to be annoying enough to stop scalping.
And honestly you probably dont want to tempt non-scalpers into being one time scalpers either.
at least for the first round till people figure it out it would totally solve it. people who actually want one get one at msrp.
the downside is you maybe dont get as many early or up front reservations from people who arent sure. but like your whole problem is more demand than supply so thats not actually an issue. and the people who can buy them for msrp will be really glad you did the thing. so you probably end out ahead on consumer side.
