Name a crypto-related technical concept that can't be explained using an analogy to mail.  I'll wait.

It's a bit of a stretch, but you could have an analogy where a flashloan is like shipping insurance.  Either your package gets delivered (your flash loan executes successfully) or you get your money back (your flash loan failed).

The post office gives you a preconf that your mail will eventually arrive at its destination (settle)

There could be some analogies here, I think!  

SSF is like mail today - once you receive it you always have it.  Reorgs would be like if the post office delivered your mail, and then came back later and demanded it back.  

BIP32 is like an address.  The top level key is the country, followed by states as children.  The states have cities as children, the cities have zip codes, etc. Eventually you end up with each leaf in the tree representing a specific address.  Since this tree represents all the addresses that exist, you can derive a specific address using the root (country) + path.

Hmm, let's try: Automated market makers, single slot finality, utxo, reorgs, hierarchical deterministic key derivation paths (BIP32).

Chat GPT helped me with this one, though it is a stretch.  Imagine that each mailman was like a Bitcoin node.  There might be a few bad mailmen out there that like to steal people's packages, or look through their packages.  So long as there aren't too many of these bad mailmen, they can't cause much harm because the post office will catch their behavior.  But if 51% of all mailmen start acting bad, then the post office loses control and these bad mailmen take over.  And now no one uses the mail, just how like a 51% attack on Bitcoin could make people stop using Bitcoin.
