lol he has a point, you can have lite nodes. But full nodes were needed for decentralization and still are. Otherwise the miners would be too powerful.
Discussion
More full nodes is never bad for decentralization. (he is saying its bad, which is retarded)
The opposite is true. The more lite nodes the more centralization because they rely on big central full nodes.
More full nodes definitely good. I can see some merchants or apps using lite nodes.
