It's a materials manufacturing to applications and lifecycle problem, not a technical one.
Graphene does 50 GPa in bulk. A single atom sheet of it does 10 MPa on its own.
Take 75 metric tonnes of cable / space elevator ribbon.
That expressed as tensile pressure at an attachment point(s) is conservatively 7.5 GPa over an area about 10 cm^2. With sensible engineering, the entire craft (a very large one) would possess a web of attachment points across its perimeter to distribute forces more-or-less evenly.
