If property deeds were on the block chain then it'd be trivial. This is a gross misunderstanding of what property deeds record or how they are recorded. Property deeds record the real property owned, using geographical features and descriptors. It's irrelevant whether deeds are stored on paper or in a blockchain, because the method of storage doesn't do anything about the features/descriptors changing. For example, if a river widens, or a tree is cut down, or plots shift because of an earthquake or ground settling, or if someone oversteps the boundaries of a plot...these are all situations covered by property insurance. The point is to make the homeowner whole for those situations where the deed as recorded (however it is recorded) no longer matches reality due to changes in the world.
