Very little of what most people do "matters" from a certain point of view. But everyone has to eat and there are plenty of products that make money that might not "matter" but offer jobs. We can't all work for Tesla or SpaceX.

if the only thing that mattered is some system being down not making some suit money, and mgmt has no respect for the work, it doesn’t matter. i work to feed myself not because it matters.

To earn a living.
