Because we need more than 8 million phone numbers. As mentioned earlier, seven digit phone numbers only allow for a little less than 8 million individual numbers (eliminating all numbers starting with a 0 or a 1 as well as certain prefixes such as 911). The area codes increases the possible numbers to just under 800 million. To throw out the existing system at this point would be costly, unwieldy, and unnecessary. By integrating area codes as part of everyone's normal phone number, the system is just evolving to accommodate capacity needs.
The first three digits of a 7-digit phone number were, and for the most part still are, geographic in nature: adding an area code is just an extension of the same process.
I've had to delete the rest of my post to instead point you to
