That doesn't prove everyone who drinks coffee is a chronic consumer. Caffeine doses are not binary, as in either you don't drink any coffee at all or are a chronic consumer otherwise.

What about those who consume it in small moderation?

Just because other people abuse it doesn't mean those who do not suffer the exact same negative effects in the same manner.

Of course studies will mostly focus on the cronic consumers as those will generally show the biggest symptoms and will be easier to study and draw conclusions versus the non coffee consumers, but that doesn't mean everyone is chronic consumer.
