Not actually true, while MakerDAO (DAI's issuer) cant microtarget and freeze, DAI itself still has alot of systematic risk, i.e. it has a large part of its backing assets in USDC, Circle could freeze this part of their balance sheet VERY easily. They also have "RWA" i.e. more traditional financial products in the mainstream financial system to generate a yield, it would be easy enough for the service providers to be ordered to freeze these assets (on the back of a money laundering or kyc type of case bought by regulators).
