I'd like to posit that at least part of the problem is we're using a multi-user operating system on machines that are universally single-user. While it may be nice to have that option, is it realistic to think that many people are going to hand over their laptop/desktop machine to another person?
We're trying to use a server OS on a single-user machine, complete with all the management cruft that comes along with a server-based OS. Consequently, we don't bother re-thinking what the user needs vs. a sysop.
Windows did that, and look at the mess that got them into. Eventually they had to introduce UAC, essentially a simplified Unix-style permissions system.
