No it is not. All that is needed is to actually use the Constitution-granted power that Congress has to limit the jurisdiction of the Federal courts. A simple majority vote of each house can completely remove certain topics from the jurisdiction of federal courts. AFAIK, that power has never been used, but it is there.
Article III, Section Section 2 "In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make."
Been there, done that for the past thirty years. How long are you suggesting we follow that failed policy?
