This is a bad argument. You're trying to say that regulation is good because in this one edge case it creates a business opportunity for some Bitcoin miners, and people are too happy about it?
It's possible that bitcoiners can be enthusiastic about something incentived by regulation because it helps to offset the mountain of other regulatory threats it faces. Also possible that people just like the idea of using waste in an innovative way.
It's not a gotcha about being hypocritical about regulation.
