Gauge theory is the most successful framework in the history of physics. Its predictive precision — the anomalous magnetic moment of the electron to ten significant figures, the prediction of the W and Z bosons, the asymptotic freedom of QCD — is unmatched. The gauge programme is one of the great intellectual achievements of the twentieth century, and this paper takes that achievement seriously. Its goal is not to dismiss what gauge theory has produced but to understand why it produces it — and why it fails where it does. The gauge-theoretic framework carries a precise ontological cost: it requires symmetry groups chosen by hand, local gauge invariance imposed as a foundational principle, compensating force carriers introduced to maintain it, nineteen free parameters in the standard model alone, and produces five structural failures — the quantum gravity problem, ultraviolet divergences, the cosmological constant problem, the measurement problem, and the string theory landscape — as consequences rather than technical difficulties. This paper argues that these five failures share a common source: the importation of continuous mathematical structures into physical ontology as foundational axioms rather than as effective large-scale descriptions of a discrete physical substrate. This diagnosis does not diminish the gauge programme's achievements — it explains them. Quantum-Geometry Dynamics (QGD), derived from two axioms about discrete space constituted by preons (−) and kinetic matter constituted by preons (+) carrying intrinsic momentum c̃, covers all the ground that gauge theory covers without its ontological overhead and without its failures. Forces in QGD are direct structural interactions: p-gravity g⁺ (a, b) = mₐ·mb, attractive between all preons (+) regardless of separation; and n-gravity g⁻ (a, b) = mₐ·mb· (d²+d) /2, repulsive between preons (−) and growing as d²/2 at large distances. No gauge bosons. No symmetry groups. No graviton. No free parameters beyond four constants determinable from experiment. The paper evaluates gauge theory and QGD against the four conditions of the Minimally Physically Derivable Theories (MPDT) metatheory, establishes that QGD satisfies all four while gauge theory satisfies none, and shows that the gauge structure of electromagnetism and general relativity emerges as the effective large-scale description of discrete preonic dynamics at scales where the individual preonic constituents are unresolvable — just as the smooth manifold of GR emerges from the isotropic preonic structure. The paper also engages the relational ontology reading of gauge freedom most clearly developed by Vidotto (2022), arguing that it draws the most coherent philosophical conclusion available within the gauge framework, but that this conclusion is better explained by a discrete foundational substrate than by the primacy of relations over intrinsic properties. The graviton does not exist in QGD: gravity is not a gauge interaction mediated by a spin-2 boson but a direct instantaneous structural interaction between preons (+). Scale-dependent expansion without dark energy, the mirror galaxy signature from the Conservation at the Boundary Theorem, and the derivation of the characteristic MOND acceleration a₀ from the force constants k and c̃ constitute the paper's distinguishing empirical predictions. The paper is part of the Quantum-Geometry Dynamics (QGD) and Minimally Physically Derivable Theories (MPDT) programme. The full programme is available on Zenodo under ORCID 0000-0002-7966-4250.
