Woodpeckers build nests in dead wood, and the insects they eat out of live wood can help keep the tree healthy. Even if it harms the tree biodiversity is good. A human with a knife does not increase biodiversity.
Unlikely that a pocket knife could do anything to a tree that is 50 years old. All the stuff on the outside is dead bark, and it’s usually thick enough to keep curious knives away from the inside.
Not to mention damaging a tree that could easily be 50+ years old.
You must think woodpeckers are the devil then

I, for one, would rather they eat from the trees than try to knock bugs off house siding

On no a tree with slightly less bark, what ever will it do?
Die, if enough bark is damaged. Suffer if less than that.
Enough is surprisingly little.

It can be surprisingly easy to damage living bark tissue with even a pocket knife.
