You're essentially asking for a whole new operating system. If the new operating system has transparent rules about resources and ownership, whether that's files or users or any other system-level entity, that sounds like a great idea. In the typical Linux model, we build programs from source with makefiles that can do anything or we install programs from package repositories with scripts that can do anything. In many cases, we even do this while running with root privileges. Sometimes people talk as if this is a great thing, but the reality is that it's crude, opaque, error-prone and dangerous. If someone suggested such a clumsy design as the foundation for almost everything we do in a new operating system today, they'd be laughed out of the room. But we tolerate it in Linux because there's so much already built that way and the cost of changing would be very high.
