And yet the technology has a lot of merit. I recently had to send off 10 pieces of irreplaceable paperwork going back 70 years for get my son his first passport. This process took months and there was every chance it might all get lost in the post.

Had all that ID existed on a government-backed blockchain as NFTs the whole process would have taken a couple of days at most.
