ASICs and GPUs do share significant dependencies in the semiconductor supply chain. Building FABS fast enough to keep up with demand is difficult and resource constrained, both by expertise and high quality materials.
You are wrong about the market value of Bitcoin’s impact on the profitability of Bitcoin mining.
Another thing to consider is that many coins still use proof of work, and an ASIC designed for one might not work for others. Some miners (especially the most scammy ones) choose the flexibility to switch coins at will. That doesn’t change the fact that ASIC now dominates, but GPUs do still have a share, especially for some of the newer scam coins.
