Sure, just like laws against mind-altering drugs have erased them from society.

As your link notes, there is no "right to be forgotten" in the US, & any attempt to bootstrap one would seem to require a partial repeal of the still-mostly-popular 1st Amendment.

A hilarious collision between US standards of free speech (& its implied right-to-remember) with the EU's 'right to be forgotten' can be seen in this NYT story about two convicted German murderers, Wolfgang Werlé and Manfred Lauber, who sued Wikipedia. The closing paragraph, especially, gave me an audible chuckle when I first read it.

There's a clear kind of "ubergovernment" tone in the responses to this thread that assumes governments are an omnipotent force. Is there a name for this, or is it common in discussions about blockchain? I suppose it's simply the other side of the coin on "uncensorable". To me the better argument against this is "no one will want to use it" vs "it's impossible to beat the government"
