If it breaks it's essentially a bug in the kernel.

If you don't see benefits of virtualization then I guess there's no convincing you, and maybe you just really don't need them. But there are people who would benefit from virtualization but don't do it because of the costs of maintaining and running a full VM, and Docker can be a good solution for them.

Python has virtual environments already. I don't see any need to host it in a guest VM.
