Bitcoin is to protect your wealth, bitcoin (layer 2) is for the coffee.

Layer 1 - Savings Layer 2 - Checking If you believe in the potential of LN, which I do at this point in time, its a fair argument to make that when you take your BTC off L1-->L2 to spend you are essentially moving wealth from savings-->checking. Not 1:1 comparison, but helps IMO

This is still somewhat analogy-fitting. We don't *have* to use analogies to define thing y'know. Bitcoin is an invention, not an iteration.

Yes, but it helps those who aren't quite able to grasp it. Laymen's terms help - not for us, but for those not in the space or for those that have a hard time conceptualizing the potential. Not direct comparison, just helps ELI5 to a parent or friend. Have to include them too!

The analogies slow the public understanding and our own ability to teach it mostly... Causes us to mis-label things. Why did we stop calling it a public ledger? L1 = worldwide ledger, slow/expensive to update. L2 = localized ledger cache, fast/cheap to update

Interesting point. I have always found that laymen's terms has helped my base level understanding (especially in Chemistry, very hard to understand things sometimes). I may have projected my personal learning style a bit. Will chew on that for the future

You seem to be thinking more in terms of enduser usage patterns while @BitcoinErrorLog is thinking more in terms of network architecture. It can be dangerous to take analogies too literally, though.

you could think of lightning as a network cache, analogous to a write back disk cache. (meaning delayed write, lots of write shadowing where things are netted out or overwritten in the cache).
