Like anything else, the answer is a very firm "it depends."
I want anybody I date to be a decent human being, the kind who makes a place better for having passed through it, or at least doesn't make it worse. Some people who do sex-related work are like that, some aren't (same as any profession).
Years ago, I dated a stripper. She was just a mom looking for the best way to support herself and her son. She wasn't in it to take advantage of anyone, or to pay for a drug habit, or because she was too lazy or venal to do any other kind of work. It was the best option for her at that point in her life, and there was nothing wrong with it.
I'd date a cam girl who was like that, for sure.
With a caveat: Solo or g/g only, no b/g because I wouldn't want to be on cam (and trust me, nobody else would want me to either) and because I wouldn't want her to be with another guy.
If I did date a cam girl, though, I think I'd insist that she be very safety conscious. I don't have a high opinion of my fellow men in general and "internet" guys in particular, so I would want to make sure she takes precautions that none of her members ever show up on our doorstep.
tl;dr: Hells yeah, long as she is awesome sauce.
P.S. As a guy on the wrong side of 40, I am totally in support of younger women/older men.
Or vice versa.
