"My point is that the nature of digital technologies is such that information is far more ephemeral and closed off than it's ever been"

I don't think I agree with that. For a lot of pre-historical research the only thing we have to go on is fossils and rock formations. Our picture about dinosaurs is extremely ephemeral and extrapolated from a very small number of things in the grand scheme of history, I don't think we can even begin to imagine the sheer number of events that happened in the total history of organic life forms that resulted in the current state of things. But knowing those things is really important for a lot of scientific fields.

Edit: Also I guess I just don't see why digital information is really significant here. It seems just as likely for a marginalized person without safety to have a physical notebook or photo album get lost or destroyed, for example.
