So that's what we expected to see. Infinite light.

Only if the universe is (not only not expanding as per current standard cosmological theories, but) infinite in both extent and age.

It makes it to Hubble's limit, c/H.

That's a misleading way of putting it (as if the light gets some distance and then stops); that simply isn't what standard physics and cosmology describe.

the evidence against the 13.8 billion number is so overwhelming

... that something like 99% of people who actually know a lot about physics and cosmology accept "the 13.8 billion number".

our galaxy has formed in less than 60 spins. [...] that formed in 20 spins.

Why should that be a problem? What aspect of our galaxy do you think requires more than 60 spins, and why?

now we have dark matter, which can basically do anything arbitrarily, just like dark energy.

It's like you aren't even trying to say things that are true (or that anyone thinks are true).

the idea that relativity is an approximation [...] is scary to people.

You should consider the possibility that people might disagree with you for reasons other than fear.
