Because you are your own bank then you have to put in a provision that in the event of any of the above ,then you have a way to recover your funds.
Death - if is a significant amount then you can always make a back up with a will and a solicitor will execute your wishes .
Fire - keep a back up some other place than your house
Loss - again you can make backups
Yes you are correct sir. Bitcoin is like you are your own bank so if something happens to you there is no way to retrieve it. I believe sharing your informations and details to your family is important so if something happens to you then they will benefit for your bitcoins.
