Yes, but I don't need the store to be online and supported to access my physical copy of an offline game. At least there's a chance I can continue playing if/when the store gets taken down.

Look at every retro console - their games still work on their platforms, and there's a second hand market for games. It's a shame they're no longer made, but at least there's a physical copy that can be traded instead of a digital copy DRM'd to an account on a store that's no longer operational.
