Why would hiding the TOTP seed in multiple locations be wrong?

It's meant to be a second factor, mostly there to prevent unsophisticated, remote/electronic attacks that affect millions of accounts.

Writing it down does not affect its ability to do that.

It reminds me of post it stickers on the monitor. Well, to be fair more like post-it stickers in a hopefully locked desk drawer.

Agreed, it will prevent any remote attacks.
