No, I don't think that is a good idea. For example, now, ICO projects are without middle-men and currently there are many fraudulent cases. Besides, investors in cryptocurrencies are now begging to have a middle - men but no one dares to assume this lofty obligation. I think, for a society to develop well, there should be many middle - men for businesses, it will create trust and legit for many other investors. then the money will flow more and better.
Not the best comparison in my opinion, you're comparing basically high-risk crowdfunding businesses to another valid industry of middle man. And there have been IEOs that have not gone anywhere and a lot of the successful ones all have fake volumes.
I reckon we could get along our lives a lot cheaper and a lot easier without a middleman in some services, although what looks to be happening is that this middleman, is quickly becoming technology and automation, and not actual men.
