Right after that ruling, I really wanted the Biden administration to construct some "official act" that would, say, cut-off power or water to the justices' houses.

Not that it would do much if most justices had no shame/principles beyond "if I like it then it's okay."

I genuinely believe that once the current administration is out of office the new President should strongly campaign in favor of the strongest possible changes to prevent dictatorship: constitutional amendments to reverse some of the most egregious harm done by the Supreme Court and the general inaction in response to fascism. Then if the opposition party isn't supportive, the new President should set a date after which they threaten to abuse their powers in exactly the same ways Trump has abused his. Surely that would motivate the opposition party, right?
