Your argument gives a good reason that targeting search engines makes no sense. But Chrome being a loss leader and Firefox and Safari being reasonable competitors give a reason targeting the browser make no sense. IE, anti-trust action against Google makes no sense, it's pure political grandstanding. "The world sucks so we should attack X powerful cog in the system" says Y powerful cogs in the system (politicians, other corporations, mass media like the NYTimes, etc).
