> But it's probably worth remembering that DNSSEC is a PKI over which the USG and its Five Eyes partnership has enormous, outsized influence; they have de facto custody over the most important TLDs on the Internet, a demonstrated willingness to intervene in DNS for policy goals, and, unlike a suborned CA, the TLDs cannot be revoked when the IC abuses them.

You're off base.

DNSSEC is not any more nebulous than the existing structure and control mechanism with regards to domain names. It (mostly) is adding cryptographic under-pinnings to the responses. The control remains the same (registrar level).
