Totally agree with you @Mielabel. The temptation of MLM isn't about being daft, it's about being vulnerable. In financial dire straits who wouldn't be tempted by a trusted friend or someone seeming to already have it all who tells you that NWM is the fast and easy way out of difficulty, be that financial, social or emotional with the only barrier being your own efforts and desires.
MLMs deliberately set a trap of easily obtainable rewards/promotions so it looks like you've found your calling and people who appreciate you as quickly as you were promised. It opens up the idea that more effort and focus will correlate with more recognition and reward. Why wouldn't you ignore the loved ones who seem sceptical? And of course that's a really hard thing to walk away from and worse, to admit you've been sold a pack of lies. Especially hard when the people in NWM are telling you that the realisation you're having means you are faulty.
I think it's the encouragement to be dissatisfied with your reality and the people around you that can be so toxic, leaving people lonely when the promises of a better life and of being a different person doesn't materialise. The problem with NWM is it sells happiness as a destination (using their map) rather than a by product of living close to one's values, being authentic and accepting oneself and circumstances. Not self-defeating but a more realistic position from which to make changes. All the empowerment talk of NWM is just a distracting noise while people get moved further away from what helps them.
I really dislike the thought control; teaching people that their thoughts control outcomes and that certain types of thoughts are dangerous and bring consequences for which the individual is responsible. It's the opposite of what is psychologically helpful. It reminds me of people with OCD who are trapped by intrusive thoughts and the belief that thinking a "bad" thought means they will do a bad thing or are a bad person, therefore they must carry out an internal or external compulsion to manage the dangerous/bad thought. Detangling thoughts from facts and demonstrating that thinking something does not cause it to happen can take a lot of work. Yet we have legions of would be NWM "coaches" encouraging people to avoid thoughts because bad thinking is dangerous and brings bad things.
The people who did have financial success in MLM often seem addicted to the validation. In Yawn's case it must be a huge part of why she keeps going. She is also still addicted to the promise of a quick turnaround in fortune. She knows she won't be able to hold down a regular job and will be hard pushed to get one with no skills or long term application for many years. She would have to start at the bottom without the excuse of being young enough to be on a steep learning curve.
