I understand this point of view, and this was also my usual approach. The reason I stopped was that the result was unmanageable systems. If you wanted to change something that you had configured on system level a year before, or even just wanted to replicate it, it became a major overhead. More creative modifications could also sometimes cause conflicts on larger upgrades.

So instead, I keep my systems small. I do not install anything I don't need, and do not touch something that is not necessary. On my laptop, I have 3 "full" applications, 15 convenience tools from homebrew (bash, git, nmap, ...) and 3 kernel extensions (including one of my own) installed. Nothing else that counts as a system-wide modification. Most of my servers are completely stock Alpine, Arch or Ubuntu systems, only running static binaries I provided.

All this saves me from dependency hell, and means that I do not need to hesitate to wipe a machine for whatever reason. It takes me 5 minutes to set a new one up, including my local own work environment.

There's a different between having control (which I have, including on my OS X machine), and actually practicing it.
