You make two very fundamental mistakes.

The first is to assume that this is about "paranoid" people. Security is 
_not_ about people who care deeply about security. It's about everybody. 
Look at viruses and DDoS attacks - the "paranoid" people absolutely depend 
on the _non_paranoid people being secure too!

The other mistake is to think that SELinux is sane, or should be the 
default. It's a f*cking complex disaster, and makes performance plummet on 
some things. I turn it off, and I know lots of other sane people do too. 
So the !SElinux case really does need to work.
