There’s a natural bias to prioritize near-term cost over long-term cost, which translates to there being a bias to just add yet another dependency. The advice is therefore to be aware of that bias and to actively work against it to counteract it. Of course, the involved trade-offs need to be considered to strike a good balance. If the stakeholders don’t enable you to strike such a balance, personally that would be an important reason to quit that situation, or to take care to not get into it in the first place.

Not everybody thinks that maintaining your own code is eventually cheaper and safer than adding a mature dependency.

Nobody said that it would. You’re putting up a straw man.
