You are not totally accurate in your comments.
The 13th and 14th amendments superseded the Dred Scott decision of 1857,
BUT!!!!!!!!!!!!!
The Supreme Court overruled it in part in Kieppe V. New Mexico (1976)
This was about state ordered protection of wild horses on federal lands within a state.
“the Court said that Congress may enact legislation governing federal lands pursuant to the property clause and “when Congress so acts, federal legislation necessarily overrides conflicting state laws under the supremacy clause.”
This writing by Justice Marshall in the decision overruled part of Scott. States could not rule what happens on federal land in their boundaries. Sometimes something that is moot can still be overruled
