It doesn't take all courts. It takes only one court across the entire country to disrupt the executive branch. In total, there are nearly 1,770 judgeships authorized across the 209 courts in the federal court system alone, and thousands and thousands of state courts. Having any one of these courts being able to disrupt the executive branch of government is not a feature of a stable governmental system. That is why the impeachment process exists. The SCOTUS merely reaffirmed what was already the law.

It appears so stable that it actually hasn't cause any of the damage you fear in over 200 years. That the chief executive is not above the law has produced the most stable democracy that's ever been conceived.
