It's as if someone invented a key you could turn to remember whatever you forgot. Great invention, but the article is saying: be aware, turning the key is not self-incrimination, and so now you have no 5th amendment.
It's not about boring people living boring lives. They can go on doing whatever and not care. This is about people whose rights get violated, people that do things, from investigative journalism, to politics, to corporate whistleblowers, etc.
And it's not just about some boring, cozy little suburbian part of the world (as if Nowheresville, Iowa and Sunville, California is all there exists), it's also about people living in oppressive regimes, fucked up governments etc.
Those people push society forward. If it were only for people whose "lives are not profound", then we would still have slavery, no women's vote, no gay rights, and 15 hour workdays (including for children).
