That is a rather simplistic argument. I mean, the House is threatening to sue Obama over executive action, among their complaints are changes in the regulations over implementation of the ACA. Of course no fix would pass through Congress, so…
Also, I doubt the insurance companies would like this suggestion very much.
But even if a way to mitigate the effects of this HL decision can be found, the damage is done.
Corporations now have religious rights. More cases will pop up over this. That can not be easily fixed. So no, I don’t think this will be irrelevant any time soon, if ever.
