Especially to take them further than they mean. Maybe he churns to sell the points and pay tuition. he already stated that he doesn't use it for what he was blamed.
Maybe? Where is it ever implied otherwise?
There was a period of time that I churned and earned, to support my family while in kollel, and to fully pay for my secular education upfront, inorder to enable us to earned a reasonable parnassah. (Maybe..).
I mean even if someone is able to churn and earn $40k a year, it has nothing to do with living a ridiculously materialistic lifestyle.
