> Users don't have to upgrade to touchbar MBPs They have, if they want anything comparable in performance to the Windows world (even though 16GB RAM tops is just laughable when there are many 64GB laptops in the Windows world, and I guess 128GB is not far around the corner...).
1) You can still buy a new 2015 MBP with a processer nearly as fast as the 2017 models and 16gb ram. But the vast majority have chosen the touchbar MBP by pure preference. 2) Laptops with more memory don’t have the same transfer speed or power efficiency.
Speed is not everything. The 2015's Skylake can't do HEVC (and VP9 but I have no idea who outside YT might use VP9).

Everything is faster and more power efficient than using swap - in fact, my MBP with nothing more than Chrome, Outlook, Slack and Excel open has 13.12GB of RAM occupied and 16.5GB swap usage. Not to mention all that swapping drastically reduces the life of the flash memory - which is, to make stuff worse, soldered on the motherboard on the 2017 model. Yet another thing that Apple forces down the throats of its users, no way to get data recovery on these when your mobo gets fried.
