Yes, if one sets up something as a virtue, whether others agree with it or not, there is satisfaction in pursuing that virtue for its own sake. And, as you both point out, it's a painless restriction, given the dizzying number of options.
That said, at some point in my wine journey, after being hammered right and left, genuinely or mostly hypocritically about the "importance of terroir," the thing I gradually came to find most fun about wine, beyond the pure sensory pleasure, was investigating, and attempting to understand, how taste varied from place to place as a function of the place, not the winemaking. Oak gradually became verboten, since it is not only a mask, but a mask from another place. The process-ethic drove the esthetic. If one could add oak, why not add cinnamon and spice and anything else one wanted? Like flavored coffee? Drawing the line at what the vine gives is a rubicon (and if rubicons are crossed, civilization of course goes to the dogs, except when it doesn't).
So, my principal interest in natural wines is not that they are better for my health (thought there is that too), or that esthetically-driven non-intervention is more virtuous than profit-driven intervention (though there is that too). I am mostly interested in the implicit attempt to get closer to the "truth of the material," a quest which, incidentally, was also important for some time in the plastic arts, when every kind of illusionism was rejected and painting had to adhere to the "flatness of the picture plane."
So, the kinds of things that "preoccupy" me in natural wine are whether techniques like carbonic and skin contact interfere with the expression of place by imposing such a strong signature on the result. Perhaps even as strong as oak, though at least, in the case of these techniques, nothing external is being added, so there wouldn't be an process-ethic issue as much an interference issue. In short, there is no lack of complexity or self-questioning involved, even in a quest that may appear to others as excessively clear cut or free from underpinnings.
