The Beirut explosion should be a wake-up call to all of us, to store your Paper wallets and cold wallets in more than one geographical location. A national disaster or a accident like this might wipe out your house and if you used that as your primary hiding place, you would lose more than your house.
Storing your crypto in multiple locations increases the risk of someone else gaining access to it. From what I've seen, the number of people who lost their crypto to theft is many times larger than the people who lost their crypto to large disasters.
This is definitely one of the disadvantages of crypto, that you truly own your own money.
It's always a trade off between the risk of losing access yourself, and someone else gaining access. I've never found a solution that fully satisfies me.
