Nothing is impossible, bt its like stopping the Gutenberg press, all we are doing is making data available to everyone and more than that the ability to add to humanities knowledge in a way that individuals retain control. This individual control of their own destiny brings responsibility though.
In terms of hard fixes for “banning” we have a decentralised community and codebase, so it all helps. The more educated we all become though the more logical this will be. Governments etc. need to allow the people their own minds, it should not be a problem but an aspect of evolution. I feel there will be roadblocks, but like all natural systems evolution is not something that can be stopped.
