To get some public services in the state of new york (unemployment or health insurance) you will be required to log into the state web site. if that was hard for you a volunteer or social worker could walk you through it at the public library.
Some people are really off the grid like the seemingly schizoprenic old woman who was living in the state forest last year. I know a single mom who lived with her daughter in a barn (both worked out OK). Other people live in underground experimental houses and will offer you raw milk from cows in a barn with way too many chickens, feathers and guano. (That lady, however, is quick to answer email despite that.)
Of course hah... what kind of question is this? If a human doesn't use one of the internet-interfacing devices like a smartphone, laptop, etc they can't use the internet. Thus they are not using the internet and have "quit" the internet.
There are plenty of people that have never used the internet, so quitting the internet depends on what dependencies you have added to it. Cut those dependencies and you can hit the power switch.
It's possible depending on how much inconvenience you can accept in your life but that's also kind of irrelevant. If you don't like something online, don't take part in it. You don't have an obligation to consume and do everything online, just pick out the parts of it that work for you.
