The best security tools and practices won't protect the business if they're not used consistently. Policy is how things get done. It's an expression of the business' values and priorities. Even if it's just "all employees must install the authenticator app or request a Yubikey otherwise the cyberinsurance will drop us."

I think you are mistaken. Obviously InfoSec is a rather generalising term, while you are abstractly describing the work of someone that works in Application Security.

I would rephrase the question... what InfoSec jobs doesn't involve spending writing documentation?

pentesting? 20% finding the low hanging fruit, 80% writing and explaining your findings.

forensics? 10% finding how they did it, 90% writing and explaining your findings.

malware/policy/security/cloud security analyst? 100% writing and explaining your findings.

the list goes on and on... you are basically and a slave for word processing software, thats why totally understand OP quitting infosec.
