Your point seems to be that there is no inherent moral good in distributing resources equally among people as opposed to allowing inequality to naturally emerge and/or optimizing for total value across all people. I don't necessarily disagree: it is hard to argue from first principles that each individual should be given the same weight, as opposed to any other arbitrary system like giving each family the same weight, or taking intelligence into account. However, it is also wrong to pretend that there isn't significant precedent in society for assigning each individual equal moral weight — for example, by allowing everyone an equal vote in elections, which has clearly been a useful practice. And I consider it obvious that "Bias based on attractiveness is no worse than bias based on personality or any other trait" isn't something that would be widely agreed upon.
