I interpreted it to mean that you can make one, and the second law will not be violated.
Not me. I think he's saying that if you look at it Maxwell's way and consider the 2nd law disproved, then none of that information theory stuff even exists. They do the information theory by assuming that the demon is sociable enough not to break the 2nd law, then they figure out exactly what he can and can't do within those rules. But there's still no argument to say he will follow the 2nd law unless you just faithfully believe that.

People then make the mistake of taking the results of information theory as proven no matter what, and using them to protect the 2nd law from the demon. But that would be circular. Bennet himself is acknowledging this circularity in the paper you found.
