By that logic, then we "disrupting" that equilibrium is also part of the equilibrium. Is it consistent to let a few adult male seals murder hundreds of pups while at the same time forbid hunters to hunt a few seals for fur, or fishermen in Faroe islands to catch dolphins once a year?
To me, it sounds that the fear of unintended consequences that you mentioned is what I called "distrust of human society". Yes, I am aware of the risk, and that's an argument that I accept in general. But it applies only at large scale, so not in the case at hand. Or we can picture an even smaller scale: picture a single old male attacking a single defenseless pup. Interfering?
The scale of animal tourism + photography is rather large, and every single time somebody sees something awful happening, we have an instinct to want to 'fix' it. Yet it's nature - stomach turning things are happening constantly. I don't know what you mean by a distrust of human society, but if you mean that I think it would rapidly grow beyond a handful of isolated incidents, then that's certainly true.
