Looking at the long-term consequences might be illuminating, though that presupposes agreement on what that long-term consequence is.

If it is a high, stable, prosperous, and happy population, sustainable over the long term, arguably good.

If you start deviating from these criteria, things don't look so good.

H-B has given us "large. Is that population stable? Is it prosperous (and if so or if not, where and why)? Is it happy? And is it sustainable over the long term? If not, what does the end-stage look like, and how does it compare to the status quo ante*, prior to H-B?

As with tackling complex projects, addressing difficult questions sometimes becomes more tractable when decomposed into sub-problems and components.

As with mathematical proofs, sometimes presuming one result, then walking that to its inevitable conclusions, leads to a proof by contradiction.
