Most people use story mode as the demo for DLC content such as weapons and vehicles, and restricting them to Online takes that from the players. Even with the Heists, cash is still hard to get, which is also why when content is in story mode it's free, but Online they want an arm and a leg for it. $75,000 for a beach buggy that was free? It all comes down to if you want it, you pay extra.
