Bitcoin does NOT remove the middleman, only physical commodity based currencies like metals do.
r0ach, you're kinda insulting everyone's intelligence here. You know darn well that you cannot transact among hundreds of thousands, millions of employees, employers, goods producers, suppliers, service providers, merchants, shippers, corporations, nations, etc. without a middleman or middle-service. At the speed/throughput needed for the world's current daily transactions (50-100k/second), peer-to-peer / face-to-face metals transactions would be impossible and unworkable.
Metals are great for wealth preservation and face-to-face snail barter, and some industry usage, but nothing more.
I will use the same argument bitcoin core uses about block size. You can create a centralized system on top of a decentralized one, but not vice versa. Using physical metals as the base unit of account and settlement (Exter's Pyramid) allows you to remove all middlemen and if you would like some other type of convenience, you can then build a centralized system on top of it. Using bitcoin as the base of unit of account or settlement gives you middlemen right out of the gate already, so it's completely useless as a form of settlement.
