I don't. My point is that there are a lot of high-status people who are not nobles, i.e. that they aren't coupled.
I don't see it that way. You're SOC 11+ you are
nobility. You are 10 or lower you are a commoner. That doesn't mean a 10 commoner might not command respect even to levels of 12 or 13, it simply means they are not
nobility.
Nobility infers something beyond simply your wealth or popularity. It is a world apart. Nobles get a pass when commoners wouldn't. That means you're, say, a knight. The guy at the customs booth takes a glance at your passport and stamps it without question. "Welcome to .... (wherever) Sir So and So."
You're a 10 you slide the guy a 100 credits and he ignores you.
As a noble you are a member of the fraternity, sorority, secret hand shake society, and that has real and tangible benefits.
The customs guy doesn't have to worry with a commoner that you are overly connected. He knows damn well if you're nobility you
are connected. There's no doubt about it.
Nobility takes care of their problems within their ranks themselves without too much publicity. Commoners end up in the justice system.
So, while SOC 10 confers some status being a noble, even a lowly Knight, means something that is tangible. Nobles literally are above the law that rules commoners. But, they screw up and there is a sort of unwritten law that nobles know they will face for doing so from their peers.
