A /128 is a single address and given the state of v6 NAT that means it can’t be shared with other machines in your network which means only your router will be able to access the v6 internet without the router being a proxy and you using it

No it means my router is not routing IPv6 traffic. It doesn't need to though. My router and all of my computers each have /128 addresses. No issues. 19/20 on ipv6-test.com.
