Of course it's a security control. Not a perfect one but a security control nonetheless. And every security control of today might become useless tomorrow so I don't get your point. Is a firewall a "guideline" just because I can tunnel some illegitimate traffic through an accepted port? Are your house and car door locks "guidelines" because a thief has to "volunteer" to not break/pick them or go in through the window? So you'll take them all out until you have "real" security controls? I guessed not...
As for your airport example, given that illegal activities go unnoticed and items are smuggled through customs every day you could argue that there are no security controls in place and that the airport relies on people volunteering to not break the law. But you'd be using the wrong definition and understanding of what a security control is.
As far as home security goes having DNS filtering adds a layer on top of the "nothing" you normally have. And it's a pretty good and accessible way to achieve this extra bit of security. "Not perfect" does not equal "no security". And it's not even just security: ad-filtering, parental controls, privacy, etc. are all impacted. DoH all but guarantees that you lose this control and unfortunately there's nothing ready to take its place.
