First of all, maybe the rest of the Aryans moved on, maybe not, but it doesn't mean the business dies. And for a lot of these characters it isn't just about the money. It wasn't about the money for Walt near the end. It was about his empire. But then his empire became another 9 to 5 job. He didn't quit because he has all the money. He quit because he was done. The money made him realize he doesn't need to work anymore. He also had ridiculous amounts of money when everyone was willing to sell for 5 million dollars. He was thinking about billions, but again it's not money for using, it was about pride status and power. And I think that is something that Todd is interested in. Or at least he was interested in making Lydia happy, who he clearly cares for. Logically, the whole business is about making money, but never underestimate greed and pride, especially when you set them against logic.
