The grandparent is meant as an example of one of the many tradeoffs that are hard to decide via objective truths. The exact details are not significant to the larger point. But along the way to the unfortunate end you describe above, many good things came of the dam. Any calculus needs to evaluate the tradeoffs. "Were they worth it?" doesn't lend itself to objective-factual analysis, because "worth" is all about values.

> one of the many tradeoffs that are hard to decide via objective truths. Those tradeoffs are "hard to decide via objective truths" only because they haven't been decomposed enough. You have to dig deeper into them, split them apart, ask why do we care about something, and then ask again and again. It might get hard to keep track of the expanding tradeoff space, which is probably why people shy away from digging into things too deep. But if you do the work, you may find out that there is a way to solve the original problem in a way that satisfies everyone's low-level values. Reminds me of essays of Bret Victor, who occasionally seems to be making a related point - a lot of policy debates quickly devolve into appeals to emotions, because we lack tools to effortlessly decompose and analyze actual problems. See e.g. http://worrydream.com/ClimateChange/#media http://worrydream.com/ClimateChange/#media for a good example.
