Surely that depends entirely on just how rough the air is?

True.

The point of rough air speed is that below that speed the structure will
be protected from breaking under the load from vertical gusts by the
wing stalling, which dramatically decreases the constant factor of the
aerodynamic forces.

There is still of course the V^2 factor, so the total force will rise
again to structural breaking point if the gusts are sufficiently strong
-- 100 m/s, say.

But at that point the speed you are flying at is irrelevant, so this
situation has no bearing on the setting of rough air speed.
