Side question: Rich seems to use etymology as a tool for original thinking and clear explanations. Are there other people who do this as well as he does?
e.g. https://www.etymonline.com/word/system - see how it's about composition, not so much about ways of doing things.
But for the sake of argument, I'm saying "complect" is neither simple *nor* easy. It's obviously not easy since it's unfamiliar. But nor is it simple, or to be really precise, no simpler than alternatives, since it doesn't conceptually improve on plain words and phrases like "complicate", "intertwine", "mix up", "separate", "tease apart", etc. It adds nothing, really.
Your comment kind of highlights some of the errors many take away from "Simple Made Easy": that ease is in opposition to simplicity and/or that they are completely orthogonal.
