I guess I don't see why the minimal and maximal approaches cannot coexist at different times. In recent years I've done a lot of traveling, and when I do, I pack light, and that is why I have cheap light equipment. I have gone to all sorts of exotic locations with a D3200 and two lenses - the 18-55 and the 55-300. I made a rare exception for Antarctica, and threw in the ancient 28/3.5 which is suited to magical landscapes and the use of a polarizer.
But at the same time, I have all sorts of other nice lenses that I use from time to time, and leave home at other times. I'll grab just about anything that looks like a bargain in a Nikon lens, and not worry a bit about how often I use it. Every once in a while, I go out and use them, and enjoy the results.
For my normal use around home, I usually have in addition to the two cheap AF kit lenses, a 35/2.8 PC that serves as my normal lens, and one of a variety of other lenses depending on mood; when I'm after birds, the 200-500; when I'm after bugs and flowers, the 85/2.8 PCD and maybe the microscope adapter with a typesetting lens or two, and when I feel like doing something different, maybe one of the old Nikkor Q lenses, and so forth. I have no qualm about having a bunch of lenses that sit around much of the time if they are any use at all. Besides, I have some old Nikon film cameras that I have no intention of selling, and they all need something to put in the holes to keep the dust out!
On the other hand, I do appreciate the purist approach too, and find that more often these days I put the 35 mm. lens on and leave the rest behind. When I was young and poor, I managed pretty well with a single normal lens, and if I had to I could again. But I'm not young and poor, and I have a big cupboard, and most of my lenses are cheaply acquired, so I feel no guilt not using them often.
