Although I agree with your point. And even I personally perceive virus as something more like machine. But your analogy opened another interpretation for me.

Person probably won't burn their house down. But some may argue that people in fact do not have problem to burn whole planet down. Like virus with the whole organism. It may be just matter of focus.

I don't think of people like I do with virus. Just that analogy opened this train of thought for me. Several different interpretations is natural feature of analogies.
