Personally, I agree with your points of view. I have avoided CEXes for years even if in some cases was to my detriment because I needed to take long and more costly (both in time and fees) routes. Even these days I prefer to trade on the internal market even if the liquidity may be insufficient (or conversions if I have to), rather than go to Binance (and go through KYC again).
But there are still enough people using them for one reason or another. And as much as I like to see our decentralized routes being developed and grown, probably a listing on Coinbase would be beneficial.
