From an ideological standpoint, it's for the people. Most "corporations" are just juggernaut middlemen. That's how they earn their bread. Walmart, Amazon, Costco.

People buy from these places because they trust they're getting the lowest price. Once blockchain is mainstream for any and all transactions, you will be able to see the margins because the supply chain will be transparent.

The security thanks to things like escrow systems would make it so that you can skip the middleman and go right to the producer, taking complete monopolistic power away from any one entity and giving more opportunity to the individual.

The future economy will have no "owners" per se, in the form of governments or corporations.
