  Thanks for the comment, this is indeed an important component! I’ve added a couple of sentences pointing in this direction.

  Sorry for the delay. As both you and TheMcDouglas have mentioned; yea, this relies on $H(C|X) = 0$. The way I’ve worded it above is somewhere between misleading and wrong, have modified. Thanks for pointing this out!

  Yea, I think you’re hitting on a weird duality between setting and erasing here. I think I agree that setting is more fundamental than erasing. I suppose when talking about energy expenditure of computation, each set bit must be erased in the long run, so they’re interchangeable in that sense.
