Your whole justification is just that some engineers have tried to guard the term by forming schools and associations. However, unlike the stupidity of Canada, it's not legal to just co-opt a common nebulous term and ban everyone else from using it in the US. Your argument as well as that Atlantic piece is just "they don't do the same things to what previous engineering fields did so it doesn't count." If that kind of stupid logic held, there would be no such thing as petroleum engineers or electrical engineers because neither of those were things for a long time.
