Without friction - climbing a rope would be impossible !
So she can reach faster

Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.
You need high friction on your climbing shoes when making contact with the rock surface, especially on small holds or slippery surfaces. High friction helps you to maintain grip and stability while ascending the rock face.
Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)
On her feet and hands. That is why they build climbing shoes from sticky rubber. Her belay partner will need friction in their belay device (ATC OR GRI GRI, etc)

Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
You need high friction so your feet and hands don't slip.
