The system boots without a default route. Then when I try to add a default route, there is this error.
The error occurs even when I completely clear the routing table.

Here is the routing table at boot:

So, if your configuration was set up properly, you wouldn't have to go back and configure the routing by hand - because that's supposed to be defined in the configuration.
Therefore, going to the core of your issue, and thanks to you including your netplan configuration, I can safely say that you have an incomplete Netplan configuration for your goals, and that's the problem you're having.
You need to tell the system a routing plan, either a default by specifying the default gateway or with custom routing plans/tables.
When network configuration is done automagically via DHCP/DHCP4, the system is told the default gateway and route to use.
When you do static, manual configuration of the network, however, you have to actually specify the routes yourself - the default route or a specialized routing rule. In this case, you need to specify the route by specifying your gateway since you're using a default route that points directly through that gateway for all data.
Try using this netplan config, which adds a gateway4 statement (which is used to specify the default route):
network:
version: 2
renderer: networkd
ethernets:
ethusb:
dhcp4: no
dhcp6: no
addresses:
- 10.0.0.120/24
- 2604:n:n:n::120/64
gateway4: 10.0.0.1
nameservers:
search: [asus]
addresses: [10.0.0.120,1.1.1.1,1.0.0.1,"2606:4700:4700::1111","2606:4700:4700::1001"]

Yup that is it. I had been assigning the IP via DHCP reservation and so had dropped the gateway from the config -- started to think I didn't need it. Then my router's DHCP reservation system became muddled (too many changes to cheap router, I guess) so I switched. thx

Including the details about how you configure your systems (DHCP vs. Static, Netplan or Network Manager, etc.) helps to solve many of the initial questions, just for the future. Thanks also for sharing your configs, it helped me to ID the exact error you were running into :)

Yup that is it. I had been assigning the IP via DHCP reservation and so had dropped the gateway from the config -- started to think I didn't need it. Then my router's DHCP reservation system became muddled (too many changes to cheap router, I guess) so I switched. thx

Try
ip route add default via 10.0.0.1?– Thomas Ward♦

@ThomasWard Yes that works. Now the route is
default via 10.0.0.1 dev ethusbCould you explain what's happening. In an answer?– Stephen Boston

@ThomasWard -- ah. But it works only in a SSH session. If i attempt through a native terminal session, I still get the error.

SSH session and Native Terminal both do the same thing you only need to add it ONCE...

I think you have something else going on that is handling networking - network manager or Netplan - you shouldn't have to add your route manually...
