There’s a clarification to be made here, in the bottom line—you were right to say that you shouldn’t be expected to believe that the big, elaborate argument violates known laws of physics if no specific step had been shown to do it, but this doesn’t mean that no such step exists. It may be that the arguer (and anyone else, for that matter) doesn’t understand a subtlety that allows the mechanism to coexist with the laws of Nature. This has happened with the proposition of the ERP experiment, when it was initially thought to violate causality, but it was later understood that there’s a distinction between causality and locality. This is also the case in many breakthroughs in engineering. The chance of this, while small, is by no means negligible, since it has happened numerous times in the past.
All that said, in the bottom line the burden of proof still lies with the claimer of a breakthrough or violation of physics.
