This suggests you believe UHC is a useful stepping stone to UBI. Is this actually your opinion? Because it doesn't reflect the vibe I got in your article. If I understand your article correctly, you believe
A) UBI is inherently fragile.
B) Conservative lobbyists will cause UBI to decay into something ugly.
C) UHC is more resilient.
D) Therefore UHC is better.
E) And France proves it.
But your comments upthread suggest you believe UHC is superior because it's easier to implement given its comfortable position within the Overton-Window. The Overton-Window Argument says it may become feasible in the future, while the Fragility Argument says it will never become feasible.
Frankly, I suspect the article is a Motte & Bailey. Maybe your real issue with UBI is that it will take too long to campaign for. I.e. you want your marshmallow sooner rather than later. Which is reasonable. But understand that it's another discussion entirely and was not clear to me from the article.
The more charitable interpretation is that you believe UBI's fragility is due to its immaturity. And that UHC will grant us experience. Okay. But if so, this was not clear to me from your article. And it would contradict your position that UBI experiments are a waste.
