The purpose is (1) deep space observation of our most plausible colonization target outside of the solar system and (2) ramping up a fault tolerant maintenance corridor for generation ships or whatever best alternative paradigm takes the place of generation ships.

What's weird here is that a lot of the criticisms just zoom in on one of the logistical steps and randomly assume it would be executed the worst way possible. I honestly don't know what distance threshold counts as necessary redundancy in this case, but if it's not 1AU (which seems too small imo), then substitute the steelmanned optimal distance and criticize that.

Suppose instead of one-time flybys it's the first half of a long trip to and from, gravity assisted by the major celestial objects of the Alpha Centauri system. I don't want to suggest that it's currently anything like a final draft, but there's ways to steelman these proposals instead of going for the low hanging fruit.

Being a philosophy major didn't convey many practical benefits to me, but one thing I did gain from it was never forgetting the importance of charitable interpretation and steelmanning.
