We're not talking about rights, we're talking about illegal acts. If it's illegal for a machine to do it, how can it be ok for a human?
Just from a rational argumentation point of view. Clearly if a law is written saying as much, then sure. But there is no such copyright law like that yet.
But machines don't do things. People do things, and they use tools/machines to do those things more easily or efficiently.
The issue is certainly not so simple. But it seems to me, purely theoretically, that the rules don't necessarily have to be the same for living people and non-living machines.
