> One thing that makes SCOTUS interesting is that they have no enforcement mechanism. It's mainly only tradition and respect for the institution that causes people to follow Supreme Court rulings
You're underselling this, I think.
It is "respect for the institution" why the military accepts the civilian authority of the POTUS as commander in chief. If we are only considering the ability to use violence to enforce one's position as legitimate, it's the military and police forces who rule. Once you factor in laws, the SCOTUS is authoritative as to how the laws can be legally interpreted.
