This is genuinely quite a scary belief coming from a SCOTUS justice. In effect he is saying that the SCOTUS is the only institution in the US that is completely untouchable by legislation. That elevates the SCOTUS to a level beyond any other government position. Effectively our benevolent overlords. Given how low of approval ratings that the SCOTUS has, their recent series of ideological activist decisions, and the fact that they aren’t even elected positions, I find myself increasingly in support of a fundamental redefinition of the SCOTUS as we know it. I don’t see why we shouldn’t stack the SCOTUS when they’ve fundamentally abandoned their duty to any level of fairness or responsibility for the citizens of the US.

Unelected, serve for life, say they are untouchable and can do as they please. How is that not a king?

Because Supreme Court cant create their own laws directly, missing legislature power, having no direct power to control national finances/budgets, a main power of a country and they dont have control of the executives including army and police. All their power depends on laws made by legislature and constitution.

Thats how the three pillars of power works in all democracies. Just because your legislature or executives or even forefathers who made the constitution fucked up, doesnt mean the supreme court is an absolute monarchy. The biggest piece of shit mistake you made was having a two party system. In other countries, supreme courts arent as binary partisan. Coalitions of Partys vote way more reasonable judges to supreme courts
