Yes, the Magsafe charger's cord is 3 feet long. Even if it was longer it would be incredibly clumsy and awkward to hold.

If you're tethered to a cord that's attached to your phone in a specific spot can you be said to not have a "port" even without part of the cable going "into" the case?

I suppose the lawyers would get paid a bunch to figure out how flexible the definition of "port" in the regulation would be. "Port" in networking is obviously purely a concept vs a physical hole. "Port" in shipping is also more conceptual, no two ports need share the same layout.
