I don't think people realize the point. I did a podcast with fiatjaf about open time stamps, when he was busy writing the implementation, and it was only during that conversation when i explained that he realized why its important, lol. I just re-listened it to see if it was worth sharing it with you, but i think you are better off with my wall of text haha.

Anyway the point was context; some old book, is physically an old book; but data is just data, it has no smell etc. So, especially in the age of A.I., you can not only conjure up data, but also a whole bunch of fake context surrounding that data. So something pretending to be very old, might as well be created mere minutes ago, including its surrounding conversation; and when over time a large quantity of keys get compromized and public knowledge the mess only becomes greater. We are better off just structurally timestamping all the things, future historians will thank us for adding some smell to the data.
