The point is that you can still treat it like a physical game. So there are upsides in that you can borrow it to your friends or resell it.
If it is a game that gets updated often or requires updates to even play it (multiplayer games) then having the game data on the card is next to worthless anyways and just makes publishing the game more difficult because they can’t start manufacturing the cards until the game is 100% ready.
Nintendo’s audience goes for physical much more than the other consoles, much easier swapping cards than dealing with family sharing, a lot of their adult users collect games, and generally Nintendo games hold their value much more so being able to resell is important. So this is a compromise between what their users want and what they need for modern game development.
Slippery slope for sure if they start doing the same with single player games but there are valid reasons for them to do this, and the alternative is they just start forcing everyone to download all of their games which is even worse. MIG switch would never have been an issue for them if there just weren’t game card slots to begin with.
Of course end users should assume the store is going to get shutdown someday and their games will be inaccessible at that time. Nintendo needs to shutdown those stores so that a couple of generations later they can sell everyone the same games for the second/third/fourth time.

The main problem is the idle power consumption. About 150w with nothing plugged in.
