And since MacPorts installs everything in a separate directory from system tools/libraries, how could it screw anything up? Like Homebrew it never installs anything outside of it's home.

But what is your point? I never meant this to be a MacPorts vs HomeBrew discussion, I've only used HomeBrew.

Being downvoted I'm obviously missing something. Care to let me know what it is instead of just downvoting me?

I'm agreeing with you, and also curious how HomeBrew and MacPorts could have screwed up any geek's laptop.
