Why didn’t anyone tell me Bitcoin was going to be volatile!? 😱😂

I don’t find any of the criticisms of BIP-300/301 to be convincing. Maybe I’m missing something, but this seems like a very elegant approach. Then again, I supported BIP-119 CTV which received vocal opposition from the broader user base, so maybe I’m not thinking adversarially enough. What is the most important reason not to move ahead with Drivechains and Blind Merged Mining?
