Yes of course someone could be socially engineered into downloading a malicious package, but that takes more effort, so whilst bad, is not an argument for removing all best security practices that have been rolled out to users in the last 5 years. what you are arguing for is a fundamentally unsafe OS that means no sensitive data can ever be safely stored there.

You are arguing that a system that allows anyone to extract data if they send a reasonably well crafted prompt is just the same as someone willing installs a programme, goes into settings to turn off a safety function and bypasses at least two warning dialogues that are trying to stop them.

if we translate this argument into say house building, your arguing that all railing and barriers to big drops are bad because people could just climb over them.
