The Judiciary (SCOTUS) is one of the branches of government, not the controlling or dominant one. In our system of checks and balances, Congress can legislate controls over the judiciary, including amending the Constitution.
In terms of legitimacy, I trust elected representatives (Congress) more than nine appointed for life black robes to reflect the will of the people. Congress needs to do more to make the Judiciary more responsible and accountable. By default, the Courts have assumed greater powers, including quasi legistlative authority. SCOTUS is not the final word nor are their opinions consistent historically. They even overrule themselves, e.g., Plessy versus Ferguson.
