Yeah, back when I was a kid I couldn't come beaming to my dad and expect praise for "Dad! Dad! I dug four holes today and then filled them up again, haven't I done good work?!" I'd have got not only a "That's not 'work', you idiot! Work is useful -- that was wasted effort!", but most probably a clip around the ear, too. And those are the norms I've internalised, so that's how my semantics swing: This whole crypto shit is inherently morally repugnant to me, because it's based on proof of waste.
