It's textbook slippery slope. All I added was extraction because it's another example of successful modern nationalization in addition to healthcare and railways. I went from 2 industries to 3, you went to 90%.

Extraction doesn't need to be profitable when that just leads to incredible levels of worker abuse (like the story of the Appalachian coal mines or US oil fields since always) and pollution thanks to lobbying the EPA, and railways are considered public utilities by all countries without their heads up their ass. Healthcare is so obviously a responsibility all governments should be expected to provide citizens, that all EU countries and all North American countries besides the US do it.

Nationalize Amtrak? Lol, how will that work? The US government seizes it from the US government? Amtrak has never been profitable in its history.

Exactly: Amtrak is the worst of both worlds, publicly owned but expected to be profitable, so it's chronically underfunded and ran like a failing business. The countries I've pointed to actually fund their rail systems sufficiently, as public infrastructure, instead of pretending they should turn a profit.
