I disagree. That's like saying we don't need to do experiments, because everything follows from a few axioms. The reason we refine theories is because they sometimes fail when pushed to their limits. Additionally, parts of a theory may be valid only certain contexts. Newton's laws work wonderfully at human scales, but not at extremes. Similarly, the Standard Model works wonderfully on the familiar things we've tested.. but maybe the Standard Model doesn't work the same way at high energies and it doesn't explain dark matter/energy anyway.. We just don't much about what black holes are like below the Schwarzschild Radius. We haven't even detected Hawking Radiation yet.
