There seem to be people who believe that the DMCA is a morally compromised instrument.

There are people that believe that using a morally compromised instrument to do a moral end is always bad.

"AI is bad because it's trained on stolen work therefore we must never use AI, even if our ends are good" is such a belief that many people seem to have, and there seems to be some likelihood that the original poster might be such a person.

Therefore it seems to me reasonable to believe that a person who maybe believes that you must never use AI because it is trained on stolen work, could also believe that you must never use the DMCA because it is based on bad and corrupted law.

I myself do not exactly believe these things, although I consider they may have some arguments for them, albeit not arguments likely to persuade me in all instances, nonetheless I do not find any difficulty in believing someone could hold both opinions at the same time and I think, in fact, it is a reasonably consistent pair of opinions, especially given the apparent ability of people to believe all sorts of inconsistent things day to day.
