Well, sure, if you can render stolen cards useless, then a host of problems go away. Maybe that will happen at scale if more card issuers decide the inconvenience/friction to legitimate card users makes it worthwhile per the level of fraud they're seeing. But, the solution to the address problem here assumes the current state of things. And, there are other issues involving addresses that strictly validating the credit card wouldn't solve (like unsolicited package and brushing scams), as well as things I'm sure we've yet to consider. In general, it would probably be a good thing for people to have better control of who can send what to their address.
