I don't see how this is more risky than traditional car keys. You've parked your car in the airport parking lot, then accidentally leave your keys in the airport bathroom. Whoever finds your keys can now steal your car.
That's not to say that this isn't a problem, but if the only way to fix it is to make access to your car dependent on Tesla's servers, that does not seem like a good trade-off. Especially since if the app can randomly stop working one day, car owners basically required to carry their keys too as a backup, and as discussed, those cannot be revoked.
