>Level of income would not be relevant to your right to take a taxi (as long as you can pay the bill), but could be relevant for a rental contract How do you define relevant? If statistically ethnicity was shown to strongly predict the chance of someone not paying their rent, would that count as "relevant"? Statistically race is predictive of many things, but in the west people have decided that racial discrimination is inherently bad because it punishes individuals for things they have no control over (their race), so the discrimination is not allowed even when justified in a statistical sense.
