We're not talking about people with disabilities, we're talking about people who are choosing to not join the rest of society and using modern technologies to sustain modern life. Someone doesn't want to do banking online? Only wants to pay cash for everything? Doesn't want to carry a cellphone? That's their choice, it doesn't mean everyone else has to act like that too or even streamline their ability to behave that way. Shops can only accept cards, banks can have a reduced number of physical locations and hours, telephone companies can stop offering payphones.
