NAT64 is a way for v6-only hosts to reach v4 hosts. I don't understand how that would apply here?
I count myself lucky, since I can at least get a public (dynamic) IPv4 address. The other option is DSLite with a single /64 via DHCP6. Well, I can't use that. So yeah, while it would be a fun journey trying out IPv6 - it's not feasable for me. And most likely, that holds true for others aswell.
There are options available - like the HE tunnelbroker - but those come with their own set of drawbacks.
