Buffer Tube . . . Maybe I'm overthinking this . . . Probably not.

[Whoops!]

With an ultra light weight bolt carrier made from 7075 aluminum, shouldn't people only be using 6061 buffer tubes? That way, the cheap buffer tube will wear and not the exceptionally expensive bolt carrier.

That, plus the lower impulse from the lighter weight bolt carrier will put less stress on the buffer tube and make its durability (if you don't fall on it, of course) less of a factor anyway.

Anyone disagree?

buffer tubes don't normally wear out. Its the stress of the steel bolt in the BCG that wears out an Al carrier.... or so is my understanding

I personally have never seen a tube wear out, but i do oil the inside lightly on all my guns.

Doesn't the bolt carrier hit the buffer, and the buffer hits the buffer tube?

I think you're overthinking it

The AL carrier will probably wear out from contact with the bolt long before the buffer tube imparts any appreciable wear to it. Your definately overthinking it.
