Well, "the grid" is not literally like "roads"; they have all sorts of difference in practice in terms of who interacts with them and in what ways... So equating them in some way is absolutely an analogy.

I wasn’t equating them. I think you might be responding to something else in the thread.

I was pointing out that the parts of our food supply chain that are infrastructure and the parts that are market driven are different parts. The problem with thinking that we have “market-driven infrastructure which provides food” is that the system which provides us food is partly infrastructure and partly market-driven, but that doesn’t mean that the infrastructure is market-driven. The infrastructure parts (e.g. roads) and market-driven parts (e.g. farms) are different parts.

There’s no analogy here, I’m not using analogies, drawing comparisons, or equating things.
