BSV is a blockchain platform that has been working well for me for this
purpose of information preservation.

It is true "rubberhosing" is usually mentioned in the context of secrecy
and privacy, but it can also be used to force erasure and destruction of
information.  In such a case it does not matter whether it is encrypted or
not: the device that holds it can be destroyed.

Additionally many can indeed coerce a large number of people.  The network
would need to preserve the information even if all parties purport to want
it removed.  Most blockchains have pulled that off, although I imagine
there are other solutions too.
