Taney’s Ruling also went far beyond slavery/abolition, into ground where those of African descent and free could not be citizens, could not become citizens, and could not have recognized human rights.
It is also a far different thing to say that a slave had no place within the nation where he could “tag” to evade ownership, from saying that an owner willingly conveying the slave to a place known to prohibit slavery could pay no heed to the local laws - and further, that someone no longer bound to slavery could not, nor anyone on their behalf, protest an attempt to reassert the ownership.
Right, and that's the reason I refer to him as "Crazy Roger" -- because his ruling was not just contrary to what our Founders believed or intended, it was also insane.
