The argument being made is: "AI is currently slop but there is a reasonable expectation that it will be pushed until it is indistinguishable from human work, and therefore devaluing of human work.

Again, if the work is ‘indistinguishable’ then I don’t see how AI art ‘devalues’ human work any more than the work done by another human. This just sounds like old fashioned competition, which has existed as long as art itself has.

I don’t like AI because it’s just another way that “corporate gonna corporate” and it never ends up working out for the mere mortals’ benefit

Corporations abusing technology to the disbenefit of people is nothing new, unfortunately, and isn’t unique to AI (see Email, computers, clocking in machines, monitoring software etc). That speaks to a need for better corporate oversight and better worker rights.

misinformation is already so prevalent and it’s going to continue to get worse (we have seen this already–trump abuses it continually).

This is a good point, but again AI is hardly the first time technology has been used to spread lies and misinformation. This highlights a fundamental problem with our media and a need to teach better critical thinking in schools etc.

They’re all valid concerns but in my opinion they suggest AI is being used as an enabler, and not that the problems in question are the sole product of it. Sadly if we stopped using anything and everything that was misused for nefarious means we’d go back to the stone age.
