Yup. I'm seeing this as well in trying to write Solarpunk fiction that has near zero hand waving of technical and economic challenges. I've had to rethink a bunch of everyday stuff that today relies on substantial heavy industry behind the scenes (like toothpaste).

I get what you mean in general, but toothpaste isn't a great example as it's not a necessity. My wife goes without it for years and has no cavity or gum issues.
