Because you're being too narrow minded. Hubble Tension exists, the universe is not consistent. We take cosmological homogeneity as an axiomatic assumption and we keep being proved wrong.

The only thing we can say with confidence is that the base laws of physics appear to be mostly consistent everywhere we've looked in the last hundred or two years. But also only across relatively recent history. The laws of physics were very different early on. The electic and magnetic field used to be separate things and now they aren't.

None of this is incompatible with science as a concept.
