That probably depends on how realistic the simulator is. Your trade off is more bias (due to simulation inaccuracy) in exchange for unlimited data (and hence less variance).
Agreed. I could see a good case of training heavily on simulated data, verify/validate on collected data.
My question is ultimately how this really helps with making the system ethical. Just moved the bias from collection to simulation. And... I can't see simulation being less impacted with bias.
