Most people who actually work don’t have time to sit in coffee houses browsing the internet and answering emails.
You might be in for a shock. Anything that can be done with "snail mail" or a phone call can be done faster and cheaper with email: customer service, processing payments, business communications, you name it. With electronic filing, any document you might want (or might be asking about) is on a server anyway.
Look at Free Republic, if you're skeptical. This has enabled American conservatives all over the world -- in South Korea, Europe, the Persian Gulf and all 50 states -- to exchange information and ideas instantly and accurately at no charge, and an accurate permanent record is created instantly and automatically. There are no filing cabinets, nor any need to build office and warehouse space for them. There are no costs for postage, stationery or long distance phone calls.
This is the way of the future. Embrace it.
These days, there is nothing that can be done on an office computer that can’t be done in a coffee shop. The company I work for provides T-mobile (Starbucks) accounts for the people who work remotely.
I can access our entire network through a VPN from home or a coffee shop.
One downside... You’re never really off the clock.
