> Some of these miss the mark, e.g. depending on what you're doing with PII storing hashes or symmetric encryptions would work fine. granted that "depending on what you're doing" is a big caveat, but: i feel like there's a difference between encrypting my PII with an ephemeral session key, then sending it in some packets across the internet that are unlikely to be captured, and encrypting my PII with some not-very ephemeral key, then writing it to the disks of thousands or millions of people with a big "this is PII" sign on top of it.

There wouldn't be a "this is PII" sign on top of it. By its nature you don't know what encrypted data is unless you can decrypt it, and there's many other things that people would be encrypting and putting on the blockchain that aren't PII (probably the vast majority of them wouldn't be). And that's only for the symmetric case anyway; in the hash case it's non-reversible and the majority of the blockchain data is already hashes anyway. Also, your "ephemeral encrypted packets" are probably logged to disk in multiple three-letter agency databases.
