there are no servers. that's the whole point. bitcoin doesn't run on a server. it runs on 17,000 nodes spread across every continent every country every timezone on earth. some in bedrooms. some in basements. some in data centers. some on raspberry pis the size of a credit card. there is no building to raid. no server room to shut down. no address to send the lawyers to. every government that ever tried to find the off switch discovered the same thing. there isn't one. you cannot kill a network that lives everywhere and nowhere simultaneously. that's not an accident. satoshi didn't forget to build the headquarters. he made sure there would never be one. because he knew that every headquarters in history eventually gets a knock on the door. bitcoin will never answer that knock. there is no door.
