I don't think it can be the same definition for every business. If it's something like a restaurant where the person can go to hundreds of other competitors, I think banning for any reason is ok. If it's large venue where there's only one, or if those restaurants band together to ban a person from the whole class of business, I don't 100% agree with it being unrestricted.

What if all the hospitals are private like in the US and they all share the same ban list? Should they be able to ban you for wearing a green shirt?

Many US hospitals are owned by government entities. Patient access to all hospitals including privately owned ones is controlled by the EMTALA law. That law doesn't apply to other types of businesses.
