I think this is where my confusion lies. It seems like many people are saying no ID of any kind -- passport, "real ID", driver's license, ... -- should be provided, period. So ostensibly a 10 year-old could show up at the airport and decide to travel on their own (and if we only ID "young-looking people" then we get into a similar discussion as to why one should always ask for proof of age when buying alcohol).

To be clear, I'm refraining from judgment on this (despite what the downvotes seem to suggest), I just want to make sure I'm understanding the distinction is not plain driver's license vs. Real ID. I don't like it very much that I have to show my ID (such as passport or European ID card) when I'm on a train in Switzerland. It seems like the majority perspective is that we shouldn't _at all_ be controlling the ID of people who get on a plane, and that's just interesting to me (it would force me to articulate what the difference is between a plane and a train ride).
