One of the main reasons why middlemen exist is trust.
When two parties have to deal with each other but cannot trust each other, then you need a "neutral" middleman that can be trusted by both. The internet will only force middle men to move there too, but the function of a middleman, not the way he works, will be needed as long as you have problems to trust someone else.
