Even if you think that there is other redistributionary harm to taxes, if we found some magic tax that didn't have any dead weight loss, and also only effects rich people, then we could at a minimum replace all existing taxes with that magic new better tax. (Perhaps total taxes could even be reduced! Because there is now extra room and value created because of the zero dead weight loss!) Therefore the point stands that if this is the case, then it would still be a massive win to find such a magic tax.
