It's not for fools like you. That is a PROFESSIONAL piece of equipment.

The intended market users will soon pay for it in their day to day
work.

Just curious, what are 80MP images used for? For magazines or brochures
less resolution is more than sufficient, so this must be for something
larger.

I'm not entirely sure that you are right. I remember some years ago
reading an article by professional landscape and nature photographer
in which he said his customers wanted a minimum of 48 Mp quality. I
can't remember the details of how he achieved this other than that it
entailed a special back on a conventional medium format camera.

If you want a 48MP image there is always mosaicing.

Not on a fashion shoot, there isn't!

Nor from the skid of a helicopter out at sea in a gale.

So, we need different tools for different assignments & circumstances.
Yet it is possible to create a 1.24TB image with Gigapan equipment and a DSLR.
