A Link-Local-Adress is only valid and guaranteed to be unique on the
Link, ie the actiual Cable or Wifi you're connected too.
When using Link-Local Adresses you *must* name the Network-Interface
they refer to:
fe80::3:9381:e382:7f69%en8
where en8 is the name of the Interface. Failing to do so, you'll see the
"Invalid argument" you reported. Try to SSH to that address, the result
will be the same.

That does not matter. You can use IPv4 and IPv6 Adresses in the same
Network (ie within the same Netmask) without a Router. The Router is
only required when you want to communicate with other Adresses outside
of your local Network.
Especially IPv6 Link Local Adresses do not even need a DHCPv6-Server or
such, they are just there and can be used in any network.
