Two reasons:
1. A sufficiently close lightning strike or other source of a massive
surge of current through a surge protector could allow the surge to
arc across the protective device in the surge protector. A 650 joule
protector is not likely to stop a 5000 joule surge.
2. Surge protectors do nothing to protect against sudden drops in
voltage such as a brief interruption of power that many power
companies provide to their customers.
3. At the price of a high rated surge protector (a few thousand
joules) you could buy an uninterruptible power supply that would
provide sufficient time to safely shut down a computer in an outage
and would also prevent lost data and/or corrupted files in a brief
power interruption. And provide excellent surge protection.
4. Have you ever read the "fine print" on one of those $250,000
guarantees? It is payable only if the surge protector fails to
perform as designed. Therefore, the guarantee on a 650 joule surge
protector that melts when hit with a 5000 joule surge is worthless.
