OP here. I edited the post to make it crystal clear that I'm advocating against centralized e-IDs. The post is meant to read as a warning, not an encouragement to go in this direction. If you read this and you're feeling revulsed at the idea of a centralized license attached to your internet connection, good. You should be.
I didn't come up with the idea of centralized e-IDs, it was already out there. It's a terrible idea, but it's exactly the kind of solution governments could be likely to go for.
I really hope this doesn't come to happen, but there has recently been an attempt by the Australian government to do just this: https://www.techdirt.com/articles/20210405/23025046557/austr...
