It is not a counterexample. Most individuals are having hard time taking into account consequences that are decades removed and either vaguely defined (e.g. 3℃ global temperature raise is a catastrophe) or too great in scope and scale (e.g. literally global societal collapse). But even so externalities are catching up. British Petroleum is pivoting into solar, for instance even if for PR reasons. As a result of external pressure (public opinion and legislation/regulation) fossil fuel industry is in decline. Most major companies are trying to diversify and do something else instead. Companies that comprise fossil fuel industry will probably remain but they'll do something else. You can not be sure you can shame or legislate paperclip maximizer, though. An average paperclip maximizer has no shame and doesn't care for any law.
