At first glance, game key cards aren't bad. It's just another option for consumers. They can have a digital product with a physical activation key. It's an interesting way to market a digital game.
The real problem is the Switch 2 itself.
First, the console comes with only 250GB of internal memory. Street Fighter VI is about 40GB. Yakuza 0 is about 50GB. Both are "game key cards", which are literally digital games. 250GB of internal memory (which also needs to include saves, images, videos, DLCs, etc.) is not acceptable for digital games. Without game key cards, you at least have the option to buy physical games, but with game key cards, about 85% of the Switch 2's current library is exclusively digital, and you're screwed when it comes to managing internal storage.
Second, and more seriously, consoles are not like PCs where you have the freedom to manage files. On Steam, a game purchased on your account can be downloaded on any computer with a compatible operating system (which includes Linux, which is free), and you can make copies of that file for your own safety. On Switch 2, only Switch 2 hardware can download the files. Your digital games are stuck not only to a single e-store, but to a single piece of hardware that will no longer be manufactured in a few years. Worse, the only store doesn't even guarantee that your download will be available in the future (pic related).
tldr:
>Game key cards themselves aren't bad.
>Switch 2 does not have enough memory to be a device for digital media
>Game Key cards made 85% of Switch 2 games exclusively digital, exacerbating the previous problem
>On top of all that, you shouldn't buy digital games on consoles because you don't have the freedom you have on PCs
