I will argue that for most cases (at least mine) 1 USB-C port would be enough. I would just revert back to the way I was using my old Thinkpad T23 back in the days - with docking station. Just use one beefy USB-C hub/dock and Bluetooth mouse if I need it on the go. The only drawback at the moment is lack of USB-C flash drives which is changing but not fast enough, so there would have to be just one USB adaptor in my bag for those rare cases when I need to plug someones flash drive.
