You literally can argue that because this claim is wrong . More samples at a lower bit depth isn't more information and higher sampling frequency past the nyquist frequency isn't actually going to capture more of the 20-20,000hz frequency range anyway. Redbook CD with pcm is already sufficiently high sample rate to reproduce the entire wave form in the range of human hearing (which is beyond what the entire adult population can hear anyway, so 100% of the people buying dacs don't hear to 20khz) the extra sampling frequency of dsd thus isn't capturing more information, its just using higher sample rate as a substitute for the higher bit depth of pcm.

Do quantization errors exist in pcm? Yes. Do quantization errors exist in dsd? Also yes. Is the noise caused by these errors inside the audible frequency range? No. But im sure your cat would prefer you use 196khz pcm instead of CD
