Do those Game key cards count as physical or digital releases?
Factually speaking, if you pull agendas and feelings out of it, they're physical releases. If you ask someone who is downright 100% against all forms of digital anything, then they're digital releases because it still is a download in a box.
But because it is tangible, you can both buy and re-sell (or trade) the game because you have second sale rights, it is a physical release.
The counter is scaring people into thinking the download won't be there 'forever' and sure, but neither is that tangible game too, it'll wear out in time.
So far Nintendo (and Sony) online networks have been up 20 years now, even if the storefront is blocked and dead, if you have a still valid ownership ID you can re-download your stuff, and even without, a game with a hot fix (like Pokemon on 3DS) it'll still download too. Yes old PSN (PSP/PS3 & VIta/PS4) and Wii/DS & WiiU/3DS networks are all still active.
To me that makes the argument idiotic, we have no idea when/if they will remove things, and if they stay up like 40-50 years is that not enough? Will my old NES games all work 50 years down the road? Maybe, maybe not. Will most people honestly care after 40+ years to maintain the stuff outside of a fringe minority of hardcore hobbyists, probably not too.
