The point is Satoshi got a lot of very fundamental stuff wrong. Bringing up
what Satoshi wrote now, almost 14 years later, misleads less-technical read=
ers
into thinking our understanding of Bitcoin is still based on that early,
incorrect, understanding.

Incidentally, you realize that it was _Satoshi_ who added RBF to Bitcoin wi=
th
nSequence replacements. My contribution was to fix that obviously broken de=
sign
with fee-based RBF (with nSequence a transaction could be replaced up to 4
billion times, using essentially unlimited P2P bandwidth; it was a terrible
idea).

Those people run mild sybil attacks on the network in their efforts to
"mitigate risk" by monitoring propagation; fundamentally doing so is
centralizing and unfair, as only a small number of companies can do that
without DoS attacking the P2P network. It's pretty obvious that reliance to
zeroconf is harmful to Bitcoin, and people trying to do that have repeatedly
taken big losses when their risk mitigations turned out to not work. Their =
only
right to be mad comes from the 1st Ammendment.

=2E..and the easiest way to avoid Bitcoin being a system that doesn't arbit=

change rules, is to rely on economically rational rules that aren't likely =
to
change!
