Exactly. There's a sucker born every minute. I'm not saying people deserve to be taken advantage of. The reality is that there will always be people who can be lead off a cliff with minimal effort. There will always be people who believe that a guy with a thick Indian accent and broken English is a representative of Microsoft and that he can fix their computer in exchange for gift card codes. There comes a point where society sacrifices too much under the pretense of protecting the gullible. Prevent people from using technology at all and they'll go back to buying actual snake oil.
This has nothing to do with keeping people safe. If it did then power users could continue to install their own software by being given that ability as a developer setting. The fact that some people are gullible enough to go into a hidden setting on their phone and enable that in order to install an app from a random Chinese website is not a good reason to take away everyone's freedom. Consolidation of power is all this is about.
