You seem to believe attraction is a requirement of sex. a lot of people will pay for sex. A lot of people also rape without care of appearance. A lot of people don’t actually care about autonomy and are single minded opportunists.
As far as addiction: opinion about how they look is inconsequential and probably non existent as they are in the throws of addiction. You’re injecting a needlessly complex ideal into the simple act of being paid to have sex or just readily available sex.
