Well the courts certainly don't. They have that "Argumentum ad antiquitatum" problem that all herd mentalities have.
They could overcome it if they just stopped looking at their predecessor's opinions and start fresh from first principles.
But they are a group think entity.
Of course the other possibility is they are just lazy, and don't want to do any work, so they just lazily go along with what their predecessors decided.
Too willing to let other people think for them instead of thinking for themselves.
I cannot commend your legal scholarship too highly. Nobody else understands the law the way you do.
