Deception often mimicks as explanation. There's not much of "explanatory power" in this analogy. The only real message a was not one of "understanding" but of associating the phenomenal success of TCP/IP to the LN, in the same way that one associates "buying cleaning products" to "be a successful housewife and have great husband and kids" in TV commercials.
This analogy is used correctly to explain that the only way to scale a blockchain is to add an additional layer. Much in the same way as you can increase the bandwidth of an Ethernet segment from 10Mb to 100Mb to 1Gb but it needs routing to making scale globally.
I cannot tell you how amusing it is that rather than address that you first start by trying to push the analogy past what it intended to explain in order to try and discredit it and now you're trying to discredit the use of analogies altogether. One might come to the conclusion that you're trying to distract attention from the fact it is correct and avoid the debate being on the subject originally intended in this thread.
