That's only a problem for exhibitors who value money over the inherent humanity of their exhibits.
I'm amused by the idea of donating my body to science, especially to medical colleges for teaching purposes, but I would want to make some kind of connection with that future. I would want people to at least know my name, see my face, have some idea that I am a person, that I want them to use what's left of me to go out and do some good in the world with it.
We're all just made out of meat, but that shouldn't dehumanize us. On the contrary. And running roughshod over human rights to put on a show does not treat its subjects humanely. Worse, that harms the audience, who gets inured to that inhumanity.
