Most games aren't that big. Especially switch games. Yes, I have a large micro SD to hold them all. I didn't say I'm not an edge case; I made it clear that silly collector shit is half the reason Nintendo has a market.
I have plenty of games I haven't played recently. That doesn't matter. The only thing that matters is that if I want to play it tomorrow, I can play it without hassle wherever I am. Anything short of that is not owning the game.
I'll have access long after the hardware gives out, with no need for the obnoxious process of ripping hundreds of cartridges. Digital is forever; DRM isn't.
I have no interest in selling a game or hardware. I never have and never will. You choose between getting half of what they'll sell it for or spending a bunch of time and trusting some random stranger not to screw you. Both options are worse than just keeping your stuff.
