Yes, that's true. It's not a solution to all the world problems. It's really a matter of dealing with the true problem. We've already seen circumstances such as these. If one wants to falsify an identity, it is possible to do so, I agree but it requires a certain effort, and the authorities can be made aware of such actions.
To my mind, it is truly necessary to recognize that this is an additional layer of security and safety. It's not a panacea.
