If the middleman brings more value to the end-customer than he increases the cost, then (s)he is a net win, and cutting the middleman out reduces the value to the end customer.
Note how that doesn't contradict what you say, which is still literally true; the question is whether your literal truth actually matters.
The Internet makes some of the old "easy" ways of being a middleman irrelevant and open the field wide open in a lot of ways, but it will never make it impossible for a middleman to bring more value to the customer than they cost. It's just that competing with "customer goes direct to the source" just got a lot harder.
