Except there will be terms and conditions that will compel mixers to kyc whoever wants to make use of their services so that they can be fished out if things go awry or authorities demand such.
That a mixer requires KYC goes against the very essence of mixers, it is something that already exists, they are called centralized exchanges, where one day they can ask for a DNA sample to be able to withdraw funds.
I still think the mixers shouldn't come back. It's an unnecessary risk.
