I can't make sense of the post; with the same reasoning, we should hope for the murder of a well-known celebrity so that we get better murder legislation.
I won't assess "better", but high profile trials do drive changes in legislation. From changes to kidnapping after the Lindbergh baby until the present day with "Caylee's Law", people need to have a stake (even a vicarious one) to really care about changing the law.
I think Cuban is right here, if you take away people's Facebook, they're going to want to know why, and they're going to be pissed when they find out.
