Pieter, what's actually happening is that the bitcoin-core release has become a Schelling point in the consensus game:

https://en.wikipedia.org/wiki/Schelling_point

Due to the strong incentives for consensus, everyone is looking for an obvious reference point that they think everyone else will also pick, even though the point itself isn't critical, only that everyone agree on whatever point is picked. Like it or not, the bitcoin-core release, and by extension it's committers have a great degree of influence over what the community as a whole decides to do. If core screws things up badly enough, yes, the community will settle on some other focal point for consensus, but the cost and risk of doing so is high, so there is indeed unavoidable moral hazard for whoever has control over any such focus point.

You present this as if the Bitcoin Core development team is in charge
of deciding the network consensus rules, and is responsible for making
changes to it in order to satisfy economic demand. If that is the
case, Bitcoin has failed, in my opinion.

What the Bitcoin Core team should do, in my opinion, is merge any
consensus change that is uncontroversial. We can certainly -
individually or not - propose solutions, and express opinions, but as
far as maintainers of the software goes our responsibility is keeping
the system running, and risking either a fork or establishing
ourselves as the de-facto central bank that can make any change to the
system would greatly undermine the system's value.

Hard forking changes require that ultimately every participant in the
system adopts the new rules. I find it immoral and dangerous to merge
such a change without extremely widespread agreement. I am personally
fine with a short-term small block size bump to kick the can down the
road if that is what the ecosystem desires, but I can only agree with
merging it in Core if I'm convinced that there is no strong opposition
to it from others.

Soft forks on the other hand only require a majority of miners to
accept them, and everyone else can upgrade at their leisure or not at
all. Yes, old full nodes after a soft fork are not able to fully
validate the rules new miners enforce anymore, but they do still
verify the rules that their operators opted to enforce. Furthermore,
they can't be prevented. For that reason, I've proposed, and am
working hard, on an approach that includes Segregated Witness as a
first step. It shows the ecosystem that something is being done, it
kicks the can down the road, it solves/issues half a dozen other
issues at the same time, and it does not require the degree of
certainty needed for a hardfork.
