It's easy to think that all travel hacks are ethical if you think price segmentation is unethical.

I'm not convinced that's true. I don't feel pricing has to be a continuous distribution that feels "fair" to be ethical. Gaps in pricing are allowed. If customers feel differently, a transparently priced airline should be able to eat everybody's lunch. That hasn't happened, which makes me think there's value to consumers to segment aggressively.
