The `ipv6_privacy` is meant to use and prefer privacy addresses as per RFC
4941. It should not has any relationships to this issue.
The `ndp -na` result shows that the neighbor cache entry for your router / gw
is stale.
fe80::1%em0 00:05:73:a0:0f:ff em0 23h56m36s S R

...
fe80::8678:acff:fe1c:ec41%em0 84:78:ac:1c:ec:41 em0 23h49m7s S R

Can you please try to ping your gw and share the ndp result?
```
# ping6 fe80::1%em0
and
# ping6 fe80::8678:acff:fe1c:ec41%em0
```
