the industry of modern pornography is absolutely incompatible with a moral society

I agree, but it isn't the sex workers who are the problem with the industry of modern pornography. It's the human traffickers, the sleazy producers, the pimps and all the other rent seeking capitalists who make the industry bad.

imagine how it will affect children when that person is someone they know in real life?

I imagine that it will humanize sex workers in the eyes of the children, whereas squirreling all of them away into the dark corners of society where they can't be seen serves to further dehumanize them.
