I have a $230 ~12" Chromebook[1], I agree with your premise of portable fan-less computer, benefits of running mobile applications and if the performance of Apple's current A series chipsets are of any indicator then one in the ARM MacBook ought to be several times better than anything intel has in this category. But, I doubt if the macOS on Apple silicon in upcoming MacBook would even fulfil all the needs of a generic consumer, if not the developers. Newer macOS releases on even current Macs have been ridden with bugs and it takes couple of major updates to fix them(the case with newer iOS releases have been worse). Many developers have stopped updating their macOS to the latest iteration and are sticking with older versions till the security updates lasts (or if Xcode support is dropped). So, IMO it's going to be a while till macOS on ARM achieves stability and the $800 is the subsidised early adopter fee to put up with its quirks.
