I've been invited to give feedback to all Parsons students, regarding your thesis projects.
I'm a big fan of your idea! You've written a very clear and actionable mission statement, and you've identified a societal behavioral "throw away" pattern that is chronic. I share your angst about used furniture cluttering alleyways, heading to the landfill. It's way too easy to discard and replace items, and there's not enough behavioral proof in place at the moment indicating a true understanding of the full cycle of products' lives in our lives.
Your proposed solution is systemic in nature, which is the kind of thinking that brings about significant (positive) change in our world. For example, you've thought about a coalition of designers "as facilitators" who get involved in addition to promoting civic engagement and creative product re-use.
Bravo! Good luck in getting this going, J.
