Having this discussion involves blasting others for not considering it. Consider the rest of the paragraph you quoted:

> But law only says what conduct it will not prevent—it does not certify that conduct as right. Aggressive tax minimization that never crosses into illegality may still be widely regarded as antisocial. A pharmaceutical company that legally acquires a patent on a long-generic drug and raises the price a hundredfold has not done something legal and therefore fine. Legality is a necessary condition; it is not a sufficient one.

If the discussion inherently cannot be had without blasting innocent bystanders, I don't think it's a discussion worth having.

It might even be morally abhorrent to have such a discussion in the first place!
