With the example of smartphones not having headphone jacks - speaking from personal experience, life is harder without a smartphone. I was smartphone free for a year and ended up having to get one to use an app for a specific government service. And providing a smartphone for myself...

Ironically enough, I'd be okay with government regulations mandating a headphone jack in phones.
