The parent's point is this. You don't own the undersea cables and Iceland doesn't either. How many companies own these cables that come into Iceland? Are those companies all from Five Eyes countries? What if the undersea cable company says stop sending traffic to this domain or we cut off your access from the data center or ISP provider side? What happens if the Five Eyes place travel/trade restrictions on Iceland unless physical data related to some alleged incident is turned over? The point being that sure no physical access is an improvement but maybe not a panacea. You may have protected data but how does that help you if it can't leave or enter your servers? The internet doesn't have to remain as free and open as it is now.
