Sure. If you're lucky enough to prioritize the things you quote above (and be able to afford said configuration every few years as needed) then yes, you should be quite the happy camper. I'm jealous.
I, on the other hand, say the non-expandable non-easily-replaceable-ness of soldered-in RAM/SSD as a result of (I assume) Apple's focus on fashion (thinness) and profit first and foremost are quite the liability. Having been able to afford a 2014 MBA i7 with full 8 gb ram but only 128gb SSD at the time, I'm quite ready to upgrade the SSD, and even RAM. But guess what my options are.... And the touch bar is horrible to work with instead of physical function keys, IMHO, which I use quite often at each use.
It would be quite interesting if Apple were to offer a 1/8" thicker (gasp!) laptop with swappable internals, even if at 30% more than I paid at the time, which I would have paid -- cost considerations of my one-and-down non-expandable MBA were quite the factor at the time of purchase... I.e., if Apple were to focus on function aspects beyond just performance which can't be later improved by the owner. It would be *very* interesting to see how consumers would shop if Apple were courageous enough to prioritize those abandoned aspects...
