I am curious if any Teslas have ever been stolen by being able to duplicate the Tesla key.

Is app + Bluetooth or the NFC cards inherently more secure than traditional key fobs?

An app can embark all modern authentication and encryption systems. You can easily secure the exchange, like we do for web today.

I imagine that the car companies either had strong hardware constraints in the key fob, or no security competency, or no interest in investing there.
