No, those layers are not to help it scale.

Those layers are different levels of abstraction that actually sit on top of one another, but encompass the lower layers.

e.g. HTTP, SMTP, POP3, etc., all sit on top of TCP — that is to say: all of those protocols actually use TCP, they are TCP, they are all made from TCP packets/communications.

TCP sits on top of IP, that is to say: all TCP packets are in fact IP packets.

They are layers of abstraction, and each layer of abstraction is not just 'related' to the lower layer(s), or 'referencing' the lower layer(s) once in a while, each of those upper layers is in fact an instance of the lower layer.

At the bottom, it's all IP. The higher layers aren't substitutes for IP that get turned into IP when necessary, they are all IP.

If your comparison was valid, then protocols such as e.g. HTTP wouldn't actually be valid TCP packets and valid IP packets, instead HTTP would be completely separate to the lower levels it is built upon, and at some point it would be converted back and forth to the other protocols. Which is not what happens.

If your comparison was valid, then all L2 cryptotoken transactions would actually simultaneously /be/ blockchain transactions — and not just written back to it periodically.

Edit:

Here's an analogy: it's like IP protocol is letters, those letters can be grouped into words, which is the next layer up, e.g. TCP, UDP, etc., and those words can be grouped into sentences, which are like the higher level protocols, such as HTTP, SMTP, POP3, etc.

Granted, the OSI model also includes lower levels, and I'm only discussing three higher layers, but the principle is the same. The higher levels /encompass/ the lower ones, they are actually built /with/ or /from/ the lower-level components. This isn't how Lighting works. It's a separate distinct network to the main blockchain, and it then writes back to blockchain.

I think the problem is that you have no clue of what the LN is and how it works.

And you can't apply your same logic to it bc of lack of understanding.

Nah, I know exactly what LN is, and how it works.

To be quite frank, based upon the fact you think the layers of OSI and TCP/IP are to help it scale, you clearly appear to have little (or no) understanding as to how that actually works — so your direct comparison to LN scaling here isn't just weak, it's meaningless and just plain factually wrong. And this is particularly obvious to folk who /do/ actually understand both.

— Good day to you, your bad logic and your poor argument.
