Can we have Hazou copy the notes on the jutsu by hand, then destroy the copy he wrote, so that he remembers how to write out the jitsu notes via muscle memory of his hand moving?
This way Naruto would still have the only copy that we've given him. Naruto can't begrudge us for remembering what we've seen out of the notes we decoded ourselves after all.
Do we really need to? Jiraiya techniques won't save our lives, aside from some overpowered ones like the Rasegan variants and we are on extremely thin ice with Naruto. He completely expect us to keep those jutsu for ourselves, so not doing so is the exactly the kind of surprising behaviour we need to show him who Hazou really is.
FOOM,Jutsu and Sealing make all but some jutsu pretty irrelevant, all things considered, in the medium-long term.
