Partisans may object "but in the abortion case it is objectively extending inward and the other perspective is the optical illusion". But that objectivity is a moral illusion.
i personally agree with the recent supreme court ruling that abortion rights shouldn't rest on privacy protections, but rather on a robust reading of the constitution that bodily autonomy is a fundamental right above and beyond states' interests (nation state or US state). i'd extend this to the issues of euthanasia and suicide as well. the state should have a very narrow and rigorously limited set of concerns (foreign relations and interstate disputes, in the case of the US federal govt).
