It helps build a new system, but all existing wallets would be hackable until they migrate. And we expect everyone to have the time and resources to do that? For a “store of value” system?

All of my hardware wallets are now worthless? All of the hardware security modules used for wallets managed by corporations no longer work?

It's an absolute mess for so many reasons that a "protocol fix" just doesn't cover.

Not necessarily. See "Discussion of Guy Fawkes signatures to protect some current bitcoins against quantum theft" and "Commit/reveal function for post-quantum recovery of insecure bitcoins" sections of the Optech page.
