We have all suspected she is dead because most of the means available to people like us would not spare us.
RBG, on the other hand, will be embalmed-alive and wired up like a cyborg in order to keep her alive.
It's not even clear if it is her choice or not. Consider for a moment that a woman is being kept alive at the edge of death for years because "The Party" needs her. It's actually kind of horrifying to contemplate being in her position as an average person.
Granted, she is not average and it is quite possible that she is fully aboard with this - but then we still get back to the problem of a lifetime appointment to the bench. There should be some cutoff - a maximum tour or something.
