My main issue with this reasoning is that if it's that unimportant that it works correctly then why build it in the first place, or waste time maintaining it. Even more time since there would be no tests to indicate what's working, what may be broken, how it may be broken etc.
I want to improve the way we develop software. My focus is on people and on tools that can help the whole team to be productive and to improve constantly. Because happy developers make happy users!

I think in many cases building a component with low test coverage is still more useful for many users than nothing at all.
