ultra pure water production itself is responsible for untold amounts of hydroflouric acid and ammonia , and most etching processes have an F-Gas involved, and most plants that do this work have tremendously high energy (power) costs due to stability needs/hvac.
The claim was that "the materials that go into a chip are nothing". Arguing that that is not that case does not really put someone on the hook to explain or even have any clue how to do it better.
Maybe. They have the potential for faster semiconductors, but only after adequate modifications. Graphene isn't a semiconductor, and it isn't obvious that we'll find a way to fix that without (or even with) rare resources.

it's not 'just sand'.
How would you suggest doing it with fewer materials?

In theory, graphene based semiconductors would eliminate a lot of need for shipping and mining.
