Because unless you are a bootlicker (or the company is yours), the company cannot possibly have all of the same values as you.

There are too many actions that are political when they come down to it (pricing products, marketing products, choosing partners, choosing tools, choosing customers, choosing features, choosing charities, etc). There is no possible way that all of them are going to align with your views.

The reason that works is that you’re just able to not care that they don’t.
