This paper presents The Economic Principles of Nature as the philosophical foundation for an attempt at unified field theory. The core scientific-philosophical view is that the universe is a self-sufficient existence without motive. It does not pursue perfection, symmetry, or infinity, but maintains self-consistency at the minimal structural cost. Asymmetry and closure are the natural default states of the universe, while symmetry and infinity are structures that require additional cost to maintain. Based on this philosophy and starting from noncommutative algebra and modular theory, this work provides a possible approach to deriving the arrow of time, the gauge structure of the standard model, three generations of fermions, and macroscopic spacetime geometry, with the three-dimensional real projective space RP³ as a tentative candidate for cosmic topology. The universe is regarded as an emergent structure from algebraic relations. This paper offers a possible philosophical and mathematical route for the unification of fundamental physics, and its validity shall be judged by experiments. fundamental physical theories;https: //doi. org/10. 5281/zenodo. 19571808 wxsq1638@outlook. com Xinyu Zheng
