After reading your post I think that you miss understood the purpose of Docker.
Even if people try to sell it has flexible silver bullet, made up for everything; like any other tools around, they need to apply some sort of CAP theorem.
Because underwoods we're just talking in how moving bits.
For instance I use containers like AWS lambda's functions. And I use tar streams to pass the contents inside them (So no virtualised mounted filesystem needed).
With that I mean you can find different way to use them, in short: Law of the instrument.
If you're wise (and according with you article you got ton of experience), you can find good purpose for it.
Docker is just 'meant' to make your life 'easier', like any other tool, not always they satisfy the expectations.
In other hands you gain experience with it, I'm sure you would use them back for a better purpose, where they can perform better for you, there is nothing to worry about this is just experience.
