I'm not sure what business model you're referring to in which it's easier to just ingest data and run analyses... but in customer-facing systems or logistics programs or online reservations software, where lots of users are passing around discreet collections of data pulled from some initial query and expected to parse back into the database after modifications, having strongly typed objects that you expect to be passed around is absolutely critical. E.g. I never worked for Lyft or Uber, but it's hard to imagine any sane way their front ends could be written without objects for routes, vehicles, waypoints, customers, payment sums, etc.
