I feel that this analogy only works if there is only one piece of content that is being replicated (downloaded) over and over again.
It seems that this tomato is created once and then replicated over and over. There is only one artist that created this tomato. It's easy to see how only one tomato creator could eventually make a good profit on his creation but in reality there are thousands (millions?) of tomato creators out there.
While I don't think that this analogy exactly falls on its face, it gets pretty diluted with each and every additional tomato variation that becomes available for replication.
