In the mean time, while we wait for IP law to fix itself over the course of decades, or probably just never: I have physical copies of most of my games.

… on an SD card, that I bought, formatted, and moved files onto.

Steam lets you make game backups, GOG releases are basically portable… make a backup, compress it, put it on a backup drive.

… and thats all without my pirate hat and pegleg on.
