One likely disadvantage of backup withholding is that Uber doesn't like to do it, because it's extra work for them. In fact, they might simply refuse to do it at your request, rather than being forced by the IRS. Another possible disadvantage is that it draws extra IRS attention to your tax returns. And doing it by choice, when it's not required, is basically unheard of, which might lead the IRS (or Uber) to investigate more closely what you're up to.
