I admire your positive view on people but I feel like you vastly overestimates both the ability to learn and the willingness to care of a huge chunk of the population. If we talk about corporate environments with hundreds of thousands of employees, you will absolutely always have malicious or drunk or just plain uncaring people that will not care at all what happens when they click that one blinking link in that one special email from the long lost relative.

The goal to teach people how technology works is admirable and necessary, but it is no defence against a motivated attacker. The attackers will always have a massive information advantage just because they have so much more time to aquire it.
