There would need to be incredible incentive for chip manufacturers to NOT go whole-hog profit. As long as they do that, they'll just follow the market.

I'm more concerned that, to exist and survive in the CBDC hellscape, existing manafacturers would be willing to submit and stop producing/shipping chips we need for ASICS
Well it wouldn't stop existing ASICs from continuing to do their thing. And there would be nation-states mining at that point.
More immediate problem to me is China invading Taiwan.
