Seems like this doesn't solve the problem, it just changes the nature of the problem from a link rot to having a single point of failure.

What assurances does perma cc give that it will continue to maintain its index for the foreseeable future as costs increase? Wayback machine is maintained by a non-profit with a charter and >$30m in annual donations/revenues. As far as I can tell Perma is maintained by a single entity (Harvard Law Library)

Not trying to be negative here but genuinely don't see how a SPOF is better than link rot.
