What a great post. You just confused the issue more and added nothing. I was trying to see if I could help explain the user permission model to the OP. Overwriting files is misbehaving doing anything but answering http requests is misbehaving.
Why complicate the issue with jails? User separation is in the same vein as user permissions, thats true. But they are hardly on the same plane. If someone is interested in understanding the basic u/g/w+chmod permissions model why would you bring up jails? Now there is twice as much to explain because you have one system+users running inside/ontop of another system+users.
Anyway breaking out of a chroot jail is not terribly hard if you have elevated priveleges above www-data inside of the chroot.
Hi, almost every post you have made in this thread has a disrespectful tone. please review what you're doing, avoid "...", don't be sarcastic, don't assume the other person is an idiot.

Oh good, a friendly one.

Jails are very easy to understand. Once you understand jails, it should be an easy logical step to understand users/groups on a conceptual/purpose level, as they can be viewed as very sophisticated jails.
