If someone is very hungry should they eat paint chips?

No, they shouldn't. They're not nourishing at all. Possibly even the opposite. Also time eating them is time they could be spending finding actual food.

If someone is lonely should they go to the internet hoping for interactions?

No, they shouldn't. It's not actually nourishing at all. And actually the interactions are usually toxic. Also it's time one could instead spend finding real live people to actually interact with.
