It was raised because someone suggested they make an OnlyFans. And it was raised again because someone believes they were not set up with a trust that was accessible when they hit 18. They don't have an active profession nor do they make a sustainable income from their social media presence (at least not anymore) - given their family and position, the only logical deduction is that they have a trust.
They don't need the branding, money, or attention that OnlyFans would provide. That is why it was brought up. You can go have several seats and then fume about the phrase, "trust fund kids".
