There's no reason to believe that the hashed and timestamped content was hosted at a particular domain, however (unless the content was signed by the author of course, then there's no Blockchain necessary). sure multiple peers could make some attestation that they saw it at that URL, but then you're back at square one of the reputation problem

Internet archive as an institution with a reputation that holds up to a judge is actually more valuable than a cryptographic proof that x bytes existed at y time

No, definitely not. I have no inherent reason to trust the people working at the Internet Archive over let's say close friend. For me trust is always a human to human concept, and no amount of tech or institutions will change that.

The more people I hear making a claim, the more I'm likely to deem the claim(s) as true. This is even true regarding the claims that cryptographic algorithms have the properties that make them useful in these contexts. I say this as someone who has even taken graduate level classes with Ron Rivest.

I'm not sure what will happen in a court. I imagine the more people that start making claims using cryptography as part of the supporting evidence, the more likely people will start to trust cryptography as a useful tool for resolving disputes about the veracity of claims.

So you would not get any value from multiple people making such claims?

Wow, thanks for sharing your perspective it's quite different from mine. For me reality is not democratic, number of people making a claim doesn't influence the truthiness of it.

I bring up judges because Internet archive captures have been used as evidence in court cases, the first one I pulled up [0] makes an interesting distinction on whether the archive's snapshots are merely hearsay:

  The hearsay rule does not apply to the document (so far as it contains the representation) if the representation was made:

  (a)    by a person who had or might reasonably be supposed to have had personal knowledge of the asserted fact; or ...

The archive's office manager submitted an affidavit to the court as someone who would have personal knowledge of the fact that the date and claimed availability of the content are accurate. There's no cryptography involved, just an individual and an institutions reputation - this carries much more weight than any number of anonymous individuals attesting to a cryptographic proof

I think the best solution is to have multiple people with reputation attest to the encrypted TLS content without being able to see the cleartext of it, that way they cant easily tamper with it.

See my comments on TLSNotary stuff below...

Woah, cool, yes, exactly this!

I think I read a paper or blog post about this concept a while ago, but never saw it implemented!
