MacOS and Windows should sandbox all apps
If giving an app all permissions is an option most apps will ask for all permissions and users will just click "Okay" so no actual safety will be added
If permissions are asked for on demand like most mobile OSes this is probably a non-issue.
When Windows introduced their "app x wants to do this, do you want to allow this" dialog, users basically always clicked yes.
Users are constantly trained to click "Yes" on permissions requests. To most users that is just "what you do to make the computer work". They do not consider it as them making a decision about security ramifications.
This is a failure of the user and not of the system. Just as the user can refuse those permissions, he can also demand to know why a calculator needs to read his emails, give bad reviews on those grounds, and call the creator a scammer..
