Then disable it. That's the great thing, when users are knowledgeable enough not to need it, they're also knowledge enough to turn it off.

I personally leave it on, it is a nice "free" fail-safe but you be you.

Your freedom is not being limited, you get control over what applications are allowed to do.

Most machines are effective single-user so security boundaries between user accounts are not very useful.

Restricting the freedom of applications is a good thing, for example I don't want steam games to be able to read my email.

The problem is that for any one who says it and means it and can represent it, many say the same, and then go crying and blaming the OS when their system is compromised and their data damaged/stolen...

So disable SIP. I do.

Do you run as root on all your systems?

I run as root when I need it.
