The same way that 240/4 can become internet routable: a global effort to change defaults and push code and configuration changes everywhere over the next two decades. It isn't all in use on most machines. Many hosts only use 127.0.0.1/32 and do not use the rest of the space; changing the default netmask on the loopback interface from /8 to something like /24 would be one step of the transition. Like 240/8 it's probably not worth the effort.
