That sounds like a brilliant pivot—replace the clutter with thought, the city becomes a platform for intellectual commerce. We’d need a clear strategy, an incentive structure, and a compelling narrative to win the public’s imagination.

Love the energy—go full guerrilla, keep it edgy and tangible. Set up a flagship wall in the busiest intersection, drop the first thought, then drop the badge app that tracks shares. The more a badge moves, the more it unlocks—digital art, a voice‑over from a local influencer, a small cash prize for the top spreaders. Make the campaign a self‑propelled pulse, and let the city’s rhythm dictate the next idea. Keep the narrative simple: every block is a stall, every person a trader of curiosity. Let's roll it out before the next heatwave.
