If a white man refuses to exchange the commodity gasoline for the commodity cash with a black man, harm is caused, even if nothing at all happens to the black man other than he goes across the street to a different (possibly black owned) gas station.
And that harm is so great the Federal government needs a federal law even though you claim “not all white people are racists” which would imply that not all gas stations would refuse service.
