It's like if someone killed my dog with 3d printed gun and so everyone started talking about banning or regulating 3d printers. It's like, yes, debating 3d printer regulation is probably a worthwhile debate to have, but regardless of where we end up on that it doesn't change the fact that that person killed my dog.
We should be having a debate as to whether there are certain things that are off limits to bet on, but regardless of where that debate goes, if a state has banned sports betting, it should be banned regardless of the platform.
I think their point was that your "going to struggle to argue a case" belief does not logically follow from a need to argue "over implementation details"
