Might be a good business in hosting servers that the mafiaa cant have confiscated.
A data haven might yet prove to be the killer Bitcoin app. The idea has been tried on several occasions, all have been crushed by outside forces. The Principality of Sealand being both the most successful and most rediculous recent example that comes to mind.
Generally speaking the Free State will not be a complete data haven. Piracy and e.g. child pornography will not be tolerated.
I can pretty much promise that copyrights would have no force in a true free market.
