Is this reasonable to do with number of softwares even average people use?

There was a person on the docker team, who had dockerized every other applications like chrome, firefox, ALSA sound server, and more. But even she found it hard to sandbox everything.

I'm using docker as a leading sandboxing tech. Do you mean something else when you mean sandbox?

I should warn that Docker was never planned as a security tool. If you read the documentation on Linux containers you will see that they are pretty complicated and therefore can have vulnerabilities.
