Would you support your 18 year old child doing onlyfans like you might them working at Disneyland?
Im not personally against Onlyfans but I won't pretend like I wouldn't have serious concerns with a loved one doing this. If for no other reason then the content being scrapped and published for future coworkers, neighbors, etc., to view.
I would support them the same way I would support them becoming a stunt actor or performing any other job that comes with significant risks - very hesitantly, while having a conversation about potential downsides and not being super happy about their choice (again, mostly due to risk to themselves), but without thinking that it is inherently some moral crime.
If my 18 kid was pulling in 120k working 6 hours a day like this, I would personally respect the hustle. If nothing else it’s a solid foundation to get a job pretending to be a politician/CEO/actor on social media etc. So there’s both better pay and more upwards mobility than most jobs available at 18.
What reason would I have to be less supportive?
