The problem was fixed by adding Linux kernel config I had overlooked:

DUMMY: needed for network commands
IP6_NF_NAT: needed for network commands
IP6_NF_TARGET_MASQUERADE: needed for network commands
NET_IPGRE: needed for network commands
NET_IPGRE_DEMUX: needed for network commands
NF_NAT_MASQUERADE_IPV6: needed for network commands

I can now add networks without error.

$ lxc network show network0
name: network0
config:
  ipv4.address: 10.76.73.1/24
  ipv4.nat: "true"
  ipv6.address: fd42:a3b6:96a3:6e7e::1/64
  ipv6.nat: "true"
managed: true
type: bridge
usedby:
- /1.0/containers/ubuntu-dev

I can also use the LXD network commands to bridge to eth0 without a
wired connection active. This completely solves my original question,
Thanks!

Network interfaces as follows in this configuration:

% sudo ifconfig
eth0: flags=-28669<UP,BROADCAST,MULTICAST,DYNAMIC>  mtu 1500
        ether (snip)  txqueuelen 1000  (Ethernet)
