In the first movie, we see Agents possessing several bluepills to be able to communicate with the Matrix. Every time something that is incompatible with survival happens, that bluepill's RSI is restored; that is, the Agents stop possessing people when they die. However, said person is still a viable source of energy, and that person was just flushed down the toilet (literally).
My question is, why didn't the machines do something to prevent that? For example, for the time that the RSI is in use, put the person in a coma. Or create a layered structure: the bluepills are in a sort of Construct, and that Construct is used as a proxy to the Matrix; whenever the person dies in the Matrix due solely to reasons simulated by the Matrix (for example, being shot), that person is then connected to a different RSI: of someone else of the same age who has died, for instance, or a new one altogether. (I believe something similar had happened with Trinity in Reloaded: she was killed within the Matrix and subsequently revived within the Matrix. She was a redpill, however, and wasn't generating energy for the machines, and was anyway on a hovercraft during the time, so that doesn't count.)
And yes, I am aware of this question, but mine is about the bluepills and not the redpills.
