"physics being solved" feels like it backs the original refinement point - we still use the formulas of Newtonian physics in non-extreme cases, and while those extremes definitely matter in important areas (nuclear power generation, semiconductors), they feel more like exceptional circumstances.

In any case, I agree with the argument for funding more general research because we don't know where the next advance will happen, and even a discovery that only applies in exceptional/narrow cases can have a lot of value.
