What if there is a 12-hour delay to unlock "power user mode", and during that entire 12-hour unlock period, the phone keeps displaying various scam education information to help even an unsophisticated user figure out what's going on? Surely Google can devote a few full-time employees to keeping such educational materials up to date, so they ideally contain detailed descriptions of the most common scams a user is going to be subject to at any given time.

This would help for sure. Ideally, the phone should stay in "expert mode" for a limited time only, like 1 hour.

However, there is still a danger that scammers will call after 12 hours, and they will be more convincing than educational material (or the user may not have read it).

It is unlikely it will work. Scammers are talking all the time and creating a sense of urgency, people have issues to think and listen at the same time, and they tend to drop thinking completely when in a haste. 12 hours of a break will give the victim time to think at least. Probably it will give time to talk about it with someone, or to google things.
