Trust and monopolies in general prevent a free market. Really socialism sin't social democracy, historically socialism is a state without a Constitution. Liberal European countries like Greenland, or Denmark aren't socials but social democracies and they identify as such. I think crypos like IOTA and Streamr are the future, streaming of live IoT data will be like trying to heard cats for the state but its possible for Trust and monopolies to control tokens and hijack us with transaction fees and transaction taxes if its not distributed property.
