Wow, you completely ignored probably the #1 reason for about 90% of the people getting into the sex industry. It's just complete non-sense without taking that into consideration and comparing it to just go get a "regular" job. LOL.
People do it for the money. But you can't be sure about how much money you could do because you don't know if people will like you and buy your stuff. So ruining your look in a attempt of making money is stupid as you have no guarantee.
And if you ask girls on why they do porn, they reply "because I need money". Yeah so ? You can earn money with tons of other jobs. So it's not a non-sens to compare it with a regular job.
