I never understood this perspective. Just because a person's behavior is market-rational, it does not mean they can't be criticized for externalities.
That is, in fact, an important thing to do. It turns those externalities into public perception, which turns into market forces that adjust the behavior, if you want to think purely in market terms.
The analogy with Budweiser is not a good one. This would be the CEO of Budweiser actively pushing more drinking while the nation's drinking was increasing. And yes, people would be right, and effective, to oppose this (see Oxycontin).
Of course they can be criticized, we can criticize the ExxonMobil CEO the same way and get nowhere
The point is, blaming them is pointless, if it wasn't them it would be someone else. How do we react?
> can't be criticized for externalities
As soon as you open up the externalities discussion, the wider question of increasing electricity prices and turbocharging global warming comes up, not to mention RAM prices. AI is a machine for turning negative externalities into stock prices.
