alt Hacker NewsDANE replaces this system with one that has the same basic cryptographic properties, but in which you can't eject bad actors --- or even monitor them with a mandatory transparency log. It's strictly worse than this.

Maybe if people implemented name constraints and the CA/B forced CAs to use them. But not as it is; unconstrained sub-CAs are a scourge on the Web PKI.
It has the property of aligning cryptographic authentication with the domain name hierarchy. Yes, you trust the hierarchy. You trust LE too, so what? We need to move away from any authority being able to authenticate anyone, and DNS naturally aligns with the goal.
You've been vocal for a long time against DNSSEC deployment too for no discernable reason.
Why are you against every single thing that tries to make DNS useful for securing anything?
WebPKI can't eject the bad actors that would cause trouble in DANE either. If your TLD conspires against you, they can certainly establish domain control and get a properly issued WebPKI cert.
Visibility through Certificate Transparency logs would at least make it a matter of record that it occurred, though.
