> Decentralized systems also make controlling your data all but impossible. If I want to remove my data from Facebook, that's the only entity that I need to deal with and it's relatively easy for regulators to set sound policies in place. In your distributed system, once your data leaves your node, you've lost all control all of it forever. That's already the case though. When I ask Facebook to delete my data they delete their copies of it. However, anyone who has downloaded photos, any advertisers who have scraped that data, any archival attempts, any search results, and a whole slew of other partial copies of that data still exist. It's almost better for data to be explicitly distributed to make it more obvious that it can't be easily removed.
