Maybe there is more.
P.E.: Human kind left sufficient footprint to be present, even while not there. This makes it possible to smell the flesh, even when it is not in the frame.
Absence of the obvious...
Finding effective absence of human trace is a real challenge, at least, here in west Europe. This could be a nice subject of a series or even the dogma of an ism.
The nohumanism.
We start a sub forum and get upset by all those rascals posting images not compliant to the dogma.
I guess you point quit accurate to the photographic caveats, technology is very dominant in the result (the image) and the process to create ‘easy mood’ is dominantly dictated by the adobe / Nikon / Fujifilm / Canon or even Nick/Google engineers.
I find converting to B/W a bit in the same corner.
Converting to black/white.
You see, I started in black/white and much of my work used to be in it too; it became the natural go-to option because of the film I loaded into the camera. Today, it still is my natural option and I believe that pretty much every shot I make with my digis is converted to black/white almost immediately it gets numbered and I start to look at it on the monitor as what it has become, and I mean prior to making if more than it's out-of-camera self - as distinct from what it was or still is in reality.
So for me, the artificiality or conversion step that disturbs your willingness to accept, is replaced instead, in my case, by the colour stored in the file. You might say: well then, buy a mono Leica. No, because I can neither afford to spend my money on things like that, nor does it let me use the internal filters that normal digital files allow. It would be a pointless sacrifice both ways. Anyhow, I prefer the way an slr functions. I understand its generic mindset very well.
The human traces. Try the local beaches during the tourist season when the people have mostly gone away to clean up and go eat. Not a pretty sight, and hardly different, one beach from another. I guess that Wabi-Sabi offers the best chances for second-stage presence, but as you suggested, hard to find emptiness anywhere unless you take up landscape, hiking and climbing up dangerous things like mountains. Include me out, as he said. Or exclude me in, it just struck me, could also make the same sort of logic.
