Having spoken with a few women that have done things adjacent to pornography, their regrets are mostly in regards to the way they were treated by people that were not in the industry. The escorts I've spoken with enjoy the work itself, although not necessarily all of the customers.
What you're saying about the horrors of pornography and prostitution apply to ALL people that need to work for a living. The company I work for buys my time, the product of my labor--which they sell for many times what I'm paid--and even my dignity by forcing me to wear a uniform of their choice. I absolutely do not like the customers that ultimately purchase the products of my labor, but I have little choice if I want to have a place to live, and food to eat.
Given that a lot of guns turned in to buyback programs have been inoperable... No. Also, there was at least once case of a guy printing a lot of pistol frames--and for most pistols, the frame is legally the firearm--and then turning them in for cash. The filament for the printer cost far less than the cash he received for each one, so he made a pretty significant profit.
