With regard to Sede-Privationism, here's the thing: Sede-Privationism says the material Pope remains a Pope-elect only. In such a case, the Bishops designated by him would remain Bishop-designates only.
No, by virtue of the appointment, they can formally exercise jurisidiction provided they have no impediment from doing so.
Also, even in straight sedevacantism, it's demonstrated quite clearly that the bishops continue to exercise jurisdiction even during interregna. Theologians were also cited to the effect that jurisdiction could even derive from Antipopes due to color of title.
You've been refuted on this point several times by the sedevacantists, but you simply ignore their arguments and keep re-stating yours.
You're perfectly free to disagree with the thesis that there can be jurisdiction in the Church during an interregnum or that color of title suffices for the transmission of jurisdiction from Christ. Jurisdiction in the Church comes from Christ, and the Pope is a conduit for it, and there's nothing that rules out that even a purely material pope could continue serving as a conduit for jurisdiction even when he cannot himself formally exercise it. Again, disagree with this, but for you to continue to assert that it's heretical is completely unwarranted.
You are not intellectually honest on this issue.
