Ken,
I will address few of the things you mentioned so hopefully it will provide further clarifications.
First, back in 2014/2015, when someone wanted to create a profile, they could either opt for Personal Information or Goverment ID, not both, it's either or. I was one of them. I didn't have my Government ID handy/scanned at that time so I opted for Personal Information without knowing what it was. But now I know what Personal Information is all about and I provided clarifications on that in my previous post.
What prompted me to reply to this thread was that a host in New Zealand asked me to upload my Government ID when I sent an inquiry to him. After having rented Airbnb in over 20 different countries around the world, this was the first host who asked for a Government ID. So that made me dug a littler deeper on this topic.
Those, who are "Verified" and have "Personal Information" as one of their verifications, CAN NOT upload a Government ID. Not online, not offline, meaning sending an email to Airbnb with your Government ID as an attachement. I had a VERY long discussion with few Airbnb folks on this. It was quite difficult to make them understand this as they themselves don't know many details. So yes, when you try to verify yourself further, it will say "Your verification is complete".
The other thing is they have different processes in place for different countries, at least that's what I was told by them. This may be true because there are few profiles I have seen which have both "Personal Information" and "Government ID" as verifications. I was quite surprised to see that and I wanted that for myself as well, however, Airbnb told me that "You are a FULLY verified member and there is nothing else to verify". So as of now, there is not any way for me to upload a Government ID.
Again, please be little more tolerant and be little more lenient towards your guests who have enough reviews for themselves which can help you look past their verifications. I know a lot of you hosts out there won't like this. But at the end of the day, please remember that when you decide to become a host, you enter yourself into a hospitality business. Yes, it's not a hotel busienss, although there are many listings which are simply hotels and hostels, but it's a relationship between a guest and a host that keeps the concept of hospitality well and alive. We both, guests and hosts, have needs and Airbnb provides the platform to satisfy those needs.
Many of the people use nicknames which can be different than their legal name or they use some form of variation of their legal name. So matching the name on Airbnb profile with the Government ID doesn't make sense in many cases. Even today, you can create a profile with one name and upload a Government ID with a different name and Airbnb will mark you as "Verified". As I had mentioned before, Airbnb doesn't have any backend process in place where they verify the authenticity of Government IDs.
There is always a solution to a problem or at least an alternative and moe creative solution to a problem. I recently made a booking in the Philippines and the host asked me to email him the copy of my Passport because they need to make a badge for me to access the apartment and other parts of the building where the apartment is. I simply need to pick the badge upon check in and need to present my Passport to verify that it matches to what I emailed to the host. This was the first for me but it's okay becasue the circumstances were different here.
So as a host if someone is really worried about the Governement ID, then you can simply state in your listing/rules that "If you are from the United States, you will have to email your Driver's License or State ID, and if you are from the outside of the United States, you will have to email your Passport, after the booking is made. No exception to this rule." So you can put something alog these lines in your listing/rules. And those guests who are genuine, and over 90% are, they will not mind doing this.
Please remember that Airbnb is still growing and learning and improving. It is still in its nascent stage. So there are a lot of opportunities for imporvements and they are working on those. They will get there. We all will get there.
Airbnb is based on the principle of trust. It is based on the principle that you can trust most of the people, both as a host and as a guest. We don't live in a perfect world and Airbnb is not an exception.
Thank you!
