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.
