If we had the resources to give 500,000 people a living wage, a home, health care, in exchange for performing a completely meaningless task then that would be a pretty good deal (that many would also be happy to take).
So no, it is not better to give people resources for performing a completely meaningless task. If the task were completely meaningless then we could provide them the same resources without requiring the labor. Neo-Luddites arguing against driverless cars are fighting the wrong thing. Their fight should be distribution of wealth created, not against innovation that increases productivity and makes our lives collectively easier.

Basically, it's foolish to have people do unnecessary work because in doing so you have squandered time and resources that could have been spent creating additional value.
Why don't we just give them the money and care instead? Then they can actually do something useful with their time.
