Protecting from scams isn't protection from the victim themselves. That should be obvious from the fact that very intelligent and technologically literate people too can fall for phishing attacks. Tell me for example, how many people in your life know how a bank would ACTUALLY contact you about a suspected hijacking and what the process should look like? And how about any of the dozens of other cover stories used? Not to mention the situations where the scammers can use literally the same method of first contact as the real thing (eg. spoofed). ...And the fact that for example email clients do their best to help them by obscuring the email address and only showing the display name, because that's obviously a good idea.
