Awesome, but you know what would be even better? If you actually owned the software licences to those games. If those licences were accessible to you. If you could do whatever you wanted with them i.e. trade, sell and transfer them. I’m sure that would suit you even better.
In an effort to appease, Microsoft could release an external usb c disc drive for the Xbox. That would allow owners of large game collections a means to play their libraries on future digital only Xbox devices.
Hell, Microsoft could offer a new medium. How about a cheap usb c mini drive, small capacity (4 MB), designed to hold an encrypted game licence key, not the entire game install. Replaces current disc based medium. Keeps physical alive and allows for the removal of the traditional disc drive. Problem solved.
