in ipv4, rfc1918 space was needed because of address scarcity. in ipv6,
you could use global space inside a nat, if you need a nat. we do not
need to perpetuate the 1918 mess.
Not having to "buy" address space, or "lease" it from whatever ISP you're using
at a certain point in time is a feature, not a workaround. RFC 1918 is only a
mess if you need to make sure multiple organizational networks do not overlap.
With the amount of subnets available in ULAs this should not be hard.
