That's the issue. Who has the problem this is solving? Last week I needed a new copy of my house keys. The next day I was going out to lunch and noticed there was a bicycle shop that copied keys down the street. I said "I'll meet you inside", got the copies made in about 2 minutes, and made it to the restaurant before the waiter had even come by to take the order. If I were a shut-in, I suppose this could be easier, but if I were a shut-in I wouldn't need more copies of my keys.
