This probably makes more sense if you view it as a boolean type, you either “have an anvil” or you don’t, and you either have access to fire or you don’t. We view a lot of things as booleans (if your clothes get wet, then wet is a boolean). This might be helpful? It connects what might seem like a sort of edge case into something familiar.
But “something that relies on itself” and “something which is usually hard to get, but easy to get more of once you have a bit of it” are a bit more special I suppose. “Catalyst” is a sort of similar yet different idea. You could graph these concepts as dependency relations and try out all permutations to see if more types of problems exists
I’m not sure I understand your point, but I think you’re pointing out that these aren’t always booleans?
There’s cases where if you’re doing well, it’s easier to do even better. Money is fairly continuous but so is friendship. (You might have acquaintances even if you don’t have close friends.) The central example of an Anvil here is boolean though; if you have enough juice in your car battery to start the car you’re fine and can charge it up more, but if you don’t have enough juice then you need someone to jump you.
