This is where Chief Justice Roberts should be remembered for a very important point he made in his infamous ACA decision a few years ago: It's not the job of the U.S. Supreme Court to fix a bad law
This approach by President Trump is perfect because it is perfectly legitimate. In fact, I've been anticipating something like this for some time.
Any federal statute that allows the feds to do things that are not authorized by the Constitution is illegal. Since the Constitution does not authorize the feds to interfere with healthcare, the ACA has NO legitimate authority and should be rejected and nullified.

Chief Justice Roberts is a turncoat and deceptive. It is not the role of SCOTUS to change the law (that would be a legislative, not a judicial function) but it is their role to strike down a law as unconstitutional if they based their ruling on sound constitutional analysis and application.
