The existence of the address space does not require nat. Being stuck in the
mindset where there is only one address on an interface leads people to
believe that nat is an automatic result local addresses. Assigning a local
prefix for local purposes (like a printer or lightswitch) at the same time
as a global prefix for those things that need to reach the Internet does not
require nat.
