Looking at what is more useful is certainly a really good idea if your goal is to calculate and understand a specific problem. But I think you would miss out on something if you ignored the question of what is fundamental. And I personally am absolutely not interested in specific problems, I want to know what really is out there. Realism? Locality? Space? Time? Particles? Fields? What is really fundamental, what are just emergent phenomena?

The question of whether or not something is 'real' is a slippery one at the scales we're talking about.
