Convince me NOT to build a (no-code) multi-vendor marketplace

Hey all, I'm likely going to build the MVP of a multi-vendor marketplace (similar to Airbnb but totally different market) using a tool like Bubble.io, or one of Shopify's integrations, possible some workaround in Webflow or also considering v0. Before I dive in, I want to get all the objections on the table, a thorough breakdown of all the bad reasons I might not be thinking of (bugs, site speed, company-killing problems if we go viral). I do have a product manager and visual designer who has decades of experience using no-code tools for prototypes and working products. Thanks!
