In Brazil you already can't access some government services without a smartphone, such as paying for municipal parking in various cities. So if you own a car but not a smartphone, you get a fine. Sadly the least of the country's problems.
There should be more noise about this here, but to whoever you talk about that issue they don't seem to grasp the situation, or simply don't care, and call you crazy/paranoid. I have been told you also need the GOV app for certain things related to companies.
