The majority of justices on the current Supreme Court have been doing a good job of sticking to the law rather than attempting to enact policy. What you’re describing is a good criticism of the mid-20th century Supreme Court, but the current Court has done a good job of rolling back those excesses.
So flip the entire thing and say Congress and the presidency were hyper-progressive. Do you not think this court would use the constitution to strike down their laws (say universal healthcare or something)? They are only rolling back these excesses because it fits their ideology.
It would be better if these were clearly codified in laws vs being on shaky ground forever. E.g Roe v Wade
