This is the same reason I store data here
The odds of it being found from here, are way way higher than if I store it on Twitter or Facebook or anywhere else, because of the historical value of blockchains, and the fact that BSV's data can be maintained (even if it can't mine blocks) by a single person.
A single person could maintain it long enough that future people were like "Wow blockchains were pretty fucking cool, this story is super fucking cool, even though they failed, and all the data is here to look through, and we could even mine blocks again for fun, and we could buy these historical items, and we can see what they were thinking at the time"
And so on
It's not a bad idea to inscribe data immutably
it's not a bad idea to hold assets on blockchains
