To be clear: I think decentralized protocols and a decentralized approach is critical to a positive future, given the risks of concentrated power over information. Don’t get me wrong. I just think the problem can’t be reduced to along a simplistic systemic axis like this. The risks are multivariate, and the potential for harm is theoretically unbounded.
There are externality risks associated with it — I can advertently or inadvertently bring you harm by effects that stem from the technology — whether or not you are party to any transaction or relationship with the creation or use thereof.
