It is as easy as compromising developers.kakao.com.
You can define every technical hack as a social problem because it
involved humans.
Yup.
The problem of DNSSEC, or PKI in general, is that, assuming such
attacks, it is equally easy to socially compromise a zone with
DNSSEC signature.
Yet that has never happened, unlike BGP attacks.
You miss my point that DNSSEC to produce correct IP addresses
is powerless against BGP attacks.
It's pretty easy to forge certificates.
Never rely on untrustworthy TTPs.
Yet I don’t hear you say to abandon TLS ?
TLS is no better than DH, which is subject to MitM attacks,
though you might hear it from me for the first time.
Because security by PKI including DNSSEC is not end to end
With TRRs in browsers like Firefox, it practically is.
Wrong.
Because it is not end to end, it is subject to MitM attacks
on software distribution chain.
Or, can you improve DNSSEC to instantly invalidate compromised
zone information, which is impossible with slowly acting CRLs.
DNSSEC has no CRLs, only TTLs. I think you meant PKI here, not
DNSSEC?
That CRLs are very slow to react against attacks because
PKI is not end to end makes CRLs totally useless for
PKIs including DNSSEC, which is why I stated "instantly
invalidate".
Socially, having long enough message IDs is as secure as DNSSEC.
“Socially” makes no sense from a protocol level.
BCP is not at the protocol level.
That is because authors of the original specification of DNSSEC
ignored my comments
It was not ignored, it was rejected.
It was ignored and rejected but later, with some implementation
efforts, was recognized resulting in specification changes in
the worst possible way, because recognition occurred to late.
So?

No implementation or code is necessary to say DNSSEC is
fundamentally hopeless.
