I think NGU is the best on boarding tool, for normies, kids, young people, old people, literally anyone. Freedom money is hard to understand, but anyone can understand number go up.

My approach in orange pilling my kids was to get them to hold and use bitcoin. I installed lightning wallets on my kids' phones and gave them bitcoin for birthdays and Christmas. As well, they can buy bitcoin from me with the fiat they earn/receive from other sources. They've experienced and saw the increase in purchasing power of their sats first hand and have a firm believe that holding value in bitcoin is far superior than holding value in fiat.

I don't think they understand the freedom money aspect of it yet, as it doesn't really concern them. But that will come later in life. At least they're stacking sats as much as possible now.

One thing to add, I don't think you can teach people something that they're not interested in or don't want to learn about. On the other hand, if they have interest in something, you don't need to teach them, as they will seek out the knowledge on their own.
