You were responding to it at #4. Congress has complete power to define the jurisdiction of the lower courts, and to make exceptions to the appellate jurisdiction of the supreme court.

Congress has complete power to define the jurisdiction of the lower courts,

Congress could establish a lower court to deal with marriage, for example. Having done so, marriage laws passed by Congress would then be subject to review by the marriage court.

Congress cannot say that no court shall review their laws.

and to make exceptions to the appellate jurisdiction of the supreme court.

Agreed. Such an arrangement could cut both ways though. "Bad" decisions by the marriage court would be final in such a scenario.
