So they could just buy supplements and other vegetables?
Eating is something one does several times a day every day of their lives. It must be done regardless of how broke or in how much of a hurry you are. I applaud anyone who chooses to add this stress to their daily lives voluntarily till the end of their days, but I'm not going to demonize someone for choosing to reject the time-intensive thing in favor of an alternative that's completely normal, cheaper, and faster.
