That's a feature, not a bug.

A human is personally responsible for a bot acting on their behalf. If your bot behaves, nothing is going to happen. If you keep handing out your personal keys to shitty misbehaving bots, then you will personally get banned - which gives you a pretty good incentive to be a bit more discerning about the bots you use.

Yes, everything should just be agnostic, as long as the incentives work out it's all fine. Like if we had worked out micropayments for the web (not saying that's a good idea per se), then who cares if you're a bot or a human when you're paying a toll either way? Flipping it to be a cost rather than payment is functionally equivalent.
