> 1) Throughout history middlemen have suffered a common fate. They get squeezed out at every opportunity. We have a chance to cut out the rent-seeking middlemen, with revolutionary new business models that allow fees to go to ~zero.
Capitalism takes care of this. Through a competitive marketplace of marketplaces, marketplaces are forced to reduce middlemen fees to the lowest necessary. Even a block-chain middlemen-less implementation will have costs associated with decentralization (see PayPal vs Bitcoin transaction fees). Fees will never achieve zero because fees cover things like fraud, service, etc, that even decentralization can't remove.
> 2) Blockchain technology gives us a censorship resistance. Not only from governments that like to ban certain types of marketplaces, but also from centralized marketplaces which like to pick and choose who is welcome on their platforms. Just look at Uber and Airbnb as examples. They have been banned in cities all around the world & have likewise banned certain individuals for life from ever using their marketplaces.
This is false. Unless your blockchain distributed app purely runs on the blockchain (has no oracles in the case of Ethereum, has no real world data dependency, has no point where it converts or interacts with the real world such as enforcing an exchange of goods) then the real world can enact regulations on it and shut it down. Silk road was hidden using Tor, but not something a distributed app can necessarily be better at. The one advantage of crypto coins is it allows internet transactions that share some properties of cash like non-reversability. Try to run a non-sanctioned cryptocoin in China to resist censorship. You will not be able to do it.
> 3) We can redistribute value to the people who actually contribute the most value in the network. Uber and Airbnb wouldn't be here today if it wasn't for the first 100 drivers/hosts, but what did those drivers/hosts get in exchange? Meanwhile, the early employees, investors and founders get filthy rich. New token economics give us a "better than free" business model that incentivizes people to use a platform that rewards early participants in the network.
The first few drivers were commodities. You measure their reward based on the risk they put in and frankly those early drivers may have been early, but certainly did not put in the risk. If anything, uber/lyft/airbnb probably served them well by giving them employment that they otherwise would not have had. So the capitalist system is already working for the most part and a crypto-anarchist system is not necessary to make this point any fairer.
> 4) Blockchain powered marketplaces are instantly global. This is a non-trivial advantage over anyone who attempts to create a centralized marketplace and has to wade through the local laws and banking regulations for each and every jurisdiction in the world where they wish to operate.
For trading in information yes since cross-border information flow is mostly unregulated (except for China). But for anything that requires shipping, until you can ship it through a fiber cable then no. Local laws and banking regulations have a purpose, and simply having a distributed app does not make it easier to circumvent laws.
