It is not their job to consider the economic implications. Their job is to advice on the public health implications. This is just advice. Government executives are expected to consider this advice, as well as the advice of economic experts when deciding what actions to take. You could, argue that executives placed undue weight in the concern of the health experts, but that would be a critisism of government executives, not health experts.
