"Steem is open source software hosted on hundreds of servers across the world, i think we will be ok."

That maybe so! But at least some of Steemit's owners are located in New York, with physical addresses. While a Court Order to obtain access keys may not result is a total shutdown of all Steemit nodes, it would result in forcing a fork of the Steem Blockchain, which would essentially mean starting over from scratch...a rather difficult task to perform with no money and only a very few members. Sure it can be done, but I doubt very much that Steemit 2.0 would have any more success than did Steemit (1.0) primarily because those who now control Steemit are just not bright enough when it comes to having the right business savvy to succeed.
