There are utilities to your idea and by that virtue, Just Buy Nothing. With a bit of contributed enhancements this could actually solve a niche problem. I'm already imagining a situation where you can opt in for a discovery/assessment after checkout; each item is assessed for utility of need vs want and whether a smaller or less expensive replacement could meet the same needs. At the end of this, a user could come off with a smaller basket that they could then take to a real shopping site and or be charged for the session. Privacy has to be nailed quickly though. Closing remarks: AI could help in the aspect of scaling the discovery/analysis with users. This was about 15 minutes of thought. There's something here for sure.
