Hello respected parties of the bitcoin network,

The point, as put forward by Jeremy is, economic rationality sometimes =
leads to breaking the =E2=80=99social contract=E2=80=99 set earlier in =
history.

Beyond its implications to RBF discussion, following economic =
rationality, rather than trying to uphold the social contract(honesty), =
may lead to hijacking of the network. Few examples: Development/Mining =
might follow the economic rational path of supporting whatever the =
blockchains winning in the market are doing (supporting smart contracts, =
or becoming a privacy chain, etc.) even at the price of giving up peer =
to peer payment system (the meme infinity/21m maybe the opposite of =
issuing multiple coins). A centralized third party may acquire the =
market sentiment to motivate this direction or influence miners/bitcoin =
dev to follow their roadmap, which seems beneficial to individuals until =
the extreme case where the core use-case is needed to secure themselves.

The main issue it seems is consensus(pow-based-vote or market sentiment =
driven improvements) cannot be vetoed by an individual(minority is not =
quite the right term, since it is opposite of majority, vs consensus). =
They can only exit at that point(, as the 'ship sails').

My point is =E2=80=98purity=E2=80=99 about Satoshi's vision(a cringe =
term at this point, but it means nothing more than the original =
=E2=80=99social contract=E2=80=99 here) should be aspired to (while not =
considering Satoshi's word as given truth, as pointed out by the bugs) & =
all =E2=80=98improvements=E2=80=99 must NOT be entertained. On the other =
hand, as pointed out by Peter & Yancy, it may be practically impossible =
to do anything better than economic rationality. (A corollary, is that =
attacks described might have already happened and thus current audience =
might be =E2=80=98unable to grok=E2=80=99 as explained by Jeremy.)

Thanks for your time, mindshare & bearing my lack of academic quality.

- S Kang
