Tell me just one thing

Why modern OS security is based on file permissions? Why not base it on what user passes to a program? If I pass a file to a function, then it has access to it. That way no malware can open backdoor without my explicit actions. It's that simple! Unix designer must be retard, it's good he is dead.

ForzenOS will have the following privilege levels for programs
each access will be checked against the privilege levels for action and can be denied. There will no "Admin user runs a virus" scenario because each privilife level has to be approved by the user himself(Add following privilege for virus.exe? Warning: This will allow the virus.exe to modify raw disk data!)
access to |read| Write/create/Send |Overwrite|Delete|Rename/Move|
