In reference to greed and limitations: that's mostly connected to banks and other financial institutions that want to essentially own your money and tell how and where it can be spent.

With the blockchain, people are free to build their own software and applications that expand upon the currency, that removes a lot of limitations and places even more opportunities to those within the currency. For example: a few years back I had heard of a startup that developed a way to transfer Bitcoin through SMS, so that people in areas with no Internet connection, but a phone network signal, could still send money instantly to another person. Consider the fact that it also created a method in which people could send money and avoid any possible censorship online, in addition.

Take a look at how Auroracoin benefited the citizens in Iceland: the coin was developed, and 50% of them were distributed among the citizens through means of identification.

So, in terms of an entirely fair distribution, there are methods of completely ensuring fairness of coins and Tokens.
