IMO, I can express the exact same sentiment, but in purely economic terms -
which will take economics out of the equation. So let me do so:

Even more importantly, is there really any scope left for design which tries
to maximize the cost/benefit integrated over the long term (which almost
always means good fundamentals-based engineering), or will we always be
restricted by short-term economic/business cost/benefit considerations to the
cheapest thing we can possibly come up quickly (which almost equally
inevitably means kludging the network into continued operation), even if
repeated application of that path choice, over the long term, has a lower
overall cost/benefit ratio than the first choice?

In other words, looked at in purely economic terms, are you trying to
optimize the short-term cost/benefit, or the long-term cost/benefit?
Economics alone won't make that choice for you.
