"on a MacBook Air cost Apple less than $10"

I don't think $200 is justified nor do I want to defend Apple... but where do you get 8GB with 100 GB/s bandwidth for $10?

I can go buy two sticks of 6400MHz DDR5 for $20 per 8GB, to match the bus width and speed. The manufacturer might be paying more than $10 for the chips, but not much more. I don't know if I should expect much price difference between DDR5 and LPDDR5?

6400 MHz * 64 bit = 51.2 GBps. Apple's laptops memory bandwidth varies between 100-400 GBps.

Regardless, I'd want Apple to have two additional LPDDR5 slots. The system could swap there or have a tiered memory.

Where did you get 64 bits though? That's a single stick, and normal devices use two sticks in parallel. They are in the range of 100GB/s.

Am I right that you as a consumer want to get the memory at the price Apple gets it from the fabs? That's a bit silly.

Right, but 20x seems like excessive

Not as silly as a 1900% markup.
