the setting is an important part of the narrative too. the tasteless commodification of sex is absolutely relevant to the overall story the game is telling.

the fact that it made you uncomfortable, or at least thought that it was too much is the point. in the future the author/designers are making a comment on sexual exploitation for profit is commonplace and has been normalised

it’s there to make the setting similar to those familiar to us from universes like blade runner, altered carbon, (to a lesser degree) firefly. it’s the standard sci-fi canon that future corporatocratic society is filled with these things: the money buys whatever you like - the basest of desires are on the table no matter what

and it’s also there in all of those universes as a comment on exploitation and morality: just because you (or rather a select few) can buy it doesn’t make it right

it may not often be part of the narrative per se, but it’s an integral part of universe building: you can’t have narrative in a void, so you need to build a convincing universe to tell the story inside
