It sounds to me like the question was supposed to read

There will certainly always be people who do pay attention to permissions for privacy or security reasons, but they seem* vastly outnumbered by the people who don't.

* Just an intuitive sense, I have not looked for data to back this up.

The point is valid, but it still doesn't address the 'general population' problem - how do you get the users to care about their security/privacy? Giving fine-grain control over permissions is a fantastic idea.. but then you realize that the 'general population' that you made this for will never touch those settings, so it's no different than telling users what permissions an application will take.

Also, the development cost of 'does this feature exist?' for each permission is pretty high.
