I just think why make it difficult to save the seed and passphrase? That will make us need to remember where we keep those things. My approach is to save those things in something that I can monitor. Keeping in 4 locations makes me difficult to watch closely because I need to go to that place and make sure that it is safe.

But if you think that is the best thing you can do to save all those things, that will be okay because we have different methods how we will keep that with us.
