I think the argument here is if you allow delivery to become a local monopoly like other utilities then just make it a utility. However as-is, there's little barrier to entry on adding delivery to any business and it should probably stay that way.
Is it necessary? No. Unfortunately I don't think would be great as a utility because quality of service matters and unlike the actual utilities, there's a lot of arbitrariness to quality of the service.
Availability of vehicles for delivery purposes is an interesting proposition. Charge doordash a tax or fee to maintain a fleet of vehicles that would open flexibility in the job market. (Consider this for ride-sharing as well... basically just reinvented the taxi medallion system but maybe with less restriction).
