Write me an exploit then
If it so insecure prove it
That is not how security works. You must protect against known and unknown attack vectors. I am only pointing out weaknesses of Docker and other linux containers that share the kernel with the host or/and run with Root. I'm not saying anything original or crazy, just read up on the security of these technologies and their limits. I am not a malware designer, I am a security researcher.
Look into gVisor and Kata Containers for info on how to improve the security of containers.
Here are some readings for you:
