I think a few physics or satcom classes might be in order. Starlink will be great for a certain, underserved segment of the population, but it will never have the same capacity or performance as modern (well run) landline or cellular infrastructures where they are available. Musk is not disputing this. He is far too smart on this subject.
There were a few overlapping edits on these posts, so my response was to a different post than now exists.
Just to be clear as to how I am approaching the math on this. Musk's proposal now appears to be up to 42,000 satellites and implying a cost on the order of $100,000 or less apiece built and in orbit.
