Such systems have existed, I will give you two guesses why they never
took off. First, it locks you into using *only* devices that actually
support it, which is exactly what the DRM of DVDs attempted to do. Ones
that decode them for OSes/devices that can't natively do so still have
to use the DRM, they just don't have to use the "approved" method. Any
system that was unbreakable, would be useless though, since you would be
forced to use it only how the distributor allowed. And.. That isn't
going to go over too well. Second, it creates conditions where the data
becomes unreadable, once the technology is passed out of use. Half the
shit produced for computers over the last 30 years either requires the
original hardware to even read, or had DRM on it, which requires
"cracking" the DRM method used, to replicate it some place else, and
even when there wasn't any DRM, simply difference in file formats, or
media formats, have rendered everything from NASA records, to old games,
to office documents, unusable.
If you care about the content persisting at all, you **can't** DRM it.
If you don't give a shit that 50 years from now the only copy requires
some device, which understands the DRM, and can read the media, of which
only one is known to even exist, then.. lock the thing up as tight as
you want. Just don't whine to the few people that managed to copy it
anyway, that you are losing revenue, or some such, over something even
*you* can't reproduce any more.
