There's far, far more to an online network and gaming service that the ability to join and play games online. The lack of unified account system, universal store, social functions (any AT ALL in-game), rewards system, and gameplay sharing all count against it (not to mention the non-interaction or gameplay perks of auto-download/install of updates/patches, etc). These things are the expectations with a new console as they're included by default by the competition. If Nintendo charged, maybe they'd be able to invest in a system that doesn't resemble what the PS2 had + Miiverse.
