Well, if the ACA is unconstitutional, which it is, then it doesn’t matter what its provisions are, because it the whole thing is invalid and should be rejected and nullified by the states and the President.
Valid presidential action here is to tell all concerned private parties and the states that they are free to simply ignore the ACA as an invalid and illegal act, and he should order a stop to any federal actions that implement or support the ACA. If there’s more to be done to undo it, then those steps should be taken.
The ACA is unconstitutional because the Constitution gives the feds no power over healthcare. Trump should NULLIFY/REJECT ENFORCEMENT OF ACA as unconstitutional but NOT try to unconstitutionally CHANGE or make new laws as an alternative and/or USE the invalid law to further unconstitutionally interfere with healthcare.
My point was the law allows for a plethora of waivers and his actions fall within that scope.
