That is a really good point and one I hadn't considered.

Is it really that easy for a single device to take down a neighborhood? For example, could a bad actor trivially disrupt a node with a modified modem? I guess that would be difficult to defend against.

I don't know enough about docsis to say if it has any protections against out-of-spec devices.

I don't know why I'm surprised when things outside my area of expertise are fragile, considering things inside my area of expertise are fragile.

Yes, similarly to how you could jam a radio frequency. Fortunately, this is rare and only ever happens due to hardware failures in modems.
