Wouldn't fusion trigger at much, much lower temperatures?
We are talking about the theoretical limit of temperature, but what is the practical limit? There's a point beyond which heating hydrogen just gets you helium and more heat, but heating anything heavier than iron gets you something colder than the inputs.
