Care to back that up with something resembling a fact.

It may or may not be strong enough in a patch or a scarphed panel but
this is a tube. Any tension on one side is compensated by equal tension
on the other.

You really don't understand what a hull does in the real world. Tension has to
be balanced by compression. Local loads have to be accommodated, not just
overall bending moments.
