When you originally proposed the scheme that may have been true. But
these days you could probably use zero-knowledge-proofs to prove that
hash digests are in fact hash digests, without having to include the
actual pre-images of those hash digests.

But Amazon doesn't offer a service to store data on S3 forever. Not even
indefinitely. The best you can do is pre-pay costs:
https://aws.amazon.com/about-aws/whats-new/2021/06/aws-now-allows-customers-to-pay-for-their-usage-in-advance-/
But even *that* service doesn't actually work in a lot of cases from
what I've heard. For example, I've heard that even if you have two
different AWS accounts, Amazon will use pre-paid funds from one to pay
the bills of another if they believe the accounts are the same
underlying entity (this is quite relevant to me as one of the ways I
backup the OpenTimestamps calendars I run is snapshots saved to S3
Glacier Deep Archive). There's also the issue that for Amazon's cheap
storage (S3 Glacier), it's quite hard for the general public to get
access to the data even if the person storing it wants to make it
available.
Comparing Bitcoin data storage/publication to centralized services like
AWS just isn't a good comparison. Like it or not, but public blockchains
are genuinely a unique service that aren't provided elsewhere.
Also of course, S3 only offers storage. Not publication. Things like
Citrea (and Lightning) specifically need data publication.

No, they do. As fees increased the hype around these tradable assets
