Yes, that's what I thinking, doing surgery just for having success in JAV. A regular JAV newcomer would do her first movies and if the sales were good, might continue if she wants or stops and go back to the normal work world. If the sales weren't good, she would directly move out of the JAV industry. Thinking "okay, so if I do PS and look like another person, maybe people will buy my movies" is stupid. What if people still didn't care ? You ruined your body for nothing (For Eimi's case, she ruined herself for let's say 3-4 years of porn fame). It's not like there are no other regular jobs around.
It's as stupid as if I wanted to be a famous actor but nobody wants to hire me because I don't stand out among others. So, I go under surgery to look like a complete different person. There are other jobs if I want to earn money. And they would avoid me to ruin my look for the rest of my life just for potential fame. There would be something wrong with me mentally if I do that.
Porn is legal. And there was an old japanese porn actor in his 80s I think. Pro athletes have short careers, same for soldiers, and many fields. You can move to another field when your first job is over, a lot of people do that. Still, some current mature actresses started in early 2000s. They take care of themself without PS, good diet and sport, that's why some are looking way better than newcomers in their 20s.
