I’d take it a step further and say that nude modeling doesn’t make a bad role model. People don’t generally get into a line of work unless they want to or are pressured into it (directly or indirectly). Someone who doesn’t want anyone to see their body won’t start a nude OF just because their favorite teacher did it. They’ll start one because they want to sell nudes or because they want to pay bills and have exhausted other options.

That last bit is more evil than any kind of voluntary sex work. People sell their bodies for worse things than sex work. Like mining, the farming work that depends on illegal immigrants (or legal ones whose bosses assume they won’t raise a stink if labour laws aren’t followed), or a bunch of factory or construction work that exposes people to fumes and dust they probably shouldn’t be inhaling. Shit that leaves them broken, or with cancer or some other disease that shortens their life. If someone can sell pictures of their bodies to avoid that kind of work, IMO that’s a good role model.
