If the need is to limit power, then why not directly limit power: make a rule stating "no more than 600bhp" or something like that? Improved technologies could still flourish. If a new approach could deliver more than the power limit, it might instead be re-tuned to provide better durability or better fuel efficiency or lighter weight. But the FIA has interfered with any of these possible paths of innovation, because it's thinking more like a government and less like a group whose very purpose is to compete.
