And many docker users run privileged containers, because then they don't need to troubleshoot permissions.. It doesn't meant the underlying system is flawed, because people take the lazy way around it.

I'm thinking of all the blogs back a few years ago for setting up things on Centos. Step 1, disable SELinux.. That was never recommended, but the blog writers didn't want to go into details about how to manage selinux, or couldn't understand it.

You're right! It's not the fault of the underlying system, it's the fault of the lazy people who work around it trivially.

With that said, some people might consider a system that is much easier to trivially work around than to use properly is one possessed of a wonderful, glorious, bountiful collection of opportunities to improve its design. Such systems are not bad! Not by any means! They just could, perhaps, be somewhat better.

All of that said, I do think a sandbox-based system probably shouldn't allow things inside the sandbox to say "Don't sandbox me bro". That seems less than maximally wise, even if it does also seem super convenient.

I almost never had to run a privileged container, and I avoid it whenever possible.

As far as I have seen, privileged container use is rare. What lead you to the assumption that it isn't?

It should also be noted that bind-mounting docker.sock is equivalent (or much worse -- it's easier to exploit at least) to using privileged containers, and an exceptionally large number of people do this (you see it in many blog posts and project installation scripts).
