Tell me it's simpler to retrofit a packaging system that distributes binaries compiled by randos on the Internet (Homebrew) to your mac just so you have access to the software you need for your work -- be it a dev environment for a given programming language, or ops tools like ansible, docker, etc... Software that all people using Linux have out of the box signed and in many cases QAd by their distro. What kind of sensible default is to have to install a packaging system on your OS?
