Steam sells non-transferable lifetime licenses to each game you “buy”, that let you play it on one PC at a time but never transfer it to anyone else, even as part of an inheritance after your death.
If you have a family there is a “sharing” plan which allows you to let family members also play some of the games in your library, but not at the same time.
Nintendo is imposing a bit more ceremony if you want to share digital games each time you share them, but the essential “one device at a time” nature is the same that steam imposes.
If we still need to buy one copy of a gamer per simultaneous player,.then the rest of the differences are just ceremony.
Nothing indicates that moving a Nintendo digital card requires uninstalling the game locally. It just, like steam, does a DRM check to see if it’s being played elsewhere.
