yes, all hosts share your frustration and there are numerous posts about the lack of guest's verification. Unfortunately, Airbnb doesn't care about the host's security, they just care about money so they will do whatever possible to make bookings as easy as possible to every guest no matter who he is. Their motto is: Belong everywhere.
But, do you know that Airbnb verification means nothing to you? Guests can change their names and profile photo whenever they want and Airbnb will never give you their personal information even if the guest attacks you or steal from you. Airbnb will (maybe) give that information to the police.
The only way we can know who has a key to our property or our home is to verify our guests by ourselves at arrival. We do that routinely. Every member of the group has to show us his ID, including children and infants. This is mandatory in some countries but we would do it even if it isn't. People behave differently if you know who they are.
