Ah, yes, in the same way that we've dealt with music piracy through law.
More seriously, people are going to have to get over the feeling that recording an event with human memory is obviously acceptable while recording an event with higher-fidelity devices is obviously not. Especially given that recordings can be faked, there is no dividing line between these. If you don't want people to remember something, don't let them know in the first place. Trying to regulate people's memory, whether internal or external, seems like a terrible idea.
