I've heard that suggestion several times.

The underlying problem is that you have routes in most peoples routing
tables which look like:

  Network Address          Netmask  Gateway Address        Interface
        127.0.0.0        255.0.0.0        127.0.0.1        127.0.0.1

And as such, anything bound for 127.x.x.x won't exit most boxes.

Instead you want something which looks like a "normal" IP address and will
get routed towards the ISP.
