Since we know exactly nothing about Roko's Basilisk

False. We can make several assertions about the Basilisk under the thought experiment. That's what I just did.

Since this most likely violates thermodynamical principles (simulation DOES require energy, the simulation of everything requires infinite energy)

Also false. Simulating a human being or even multiple human beings or even every human being in existence does not require infinite energy. Simulating one person probably doesn't even require a lot of energy at all.
