The operations are non-trivial. UberEats, DoorDash, GrubHub et al all have full-time operations personnel in nearly every market they operate. Operationalizing this requires things like fraud/risk protection, order defect minimization, courier safety, refunds/chargeback adjudication etc. Not to say that this CANNOT be done in a decentralized, OSS way — but it's not just a CRUD app.
