Who exactly is going to route/send an RFC1918 address to an Internet gateway?
Are you implying your ISP itself is going to do this? Because the Internet at-large doesn't have routes for your internal address space.

The GP is talking about 1:1 'basic' NAT:

The same problem applies to masquerading. Routers are happy to route packets they receive, and NAT (in whatever form) isn't the tool you use to drop those packets.
