Stating in your argument “there are no arguments to this” highlights up front how close-minded you are to discussion on the subject. It’s perfectly acceptable to discuss things you strongly believe in while still allowing yourself to be open-minded about opposing views. In fact, I would say it is required for honest discourse to occur.
In my personal experience, I have one of these vehicles with a comfortable and spacious cab. It allows me to have one vehicle for all the tasks that come with a sheep and pig farm, and also allows us to transport our large family comfortably to and fro. I would like my family to be comfortable while riding in our vehicle, which is equally able to perform various work functions related to farming and transport a family. Why would we purchase and maintain two separate vehicles for these purposes when a single option exists?
Corn, wheat, and other farmers have separate vehicles to accomplish the tasks necessary for their farms, e.g. a combine harvester, seeder, iriggator, etc. I know they also have large spacious trucks as well, but my point is that it is feasible to expect an agricultural business owner, or any buisness owner, to have different commercial equipment for different tasks related to their industry. Besides, whereas all the people who need pickups for their business have them, not all pickup owners need their vehicles for business. I see many, many large pickups parked in residential areas of the city and around the suburbs. The closest most of those people get to agribusiness is going to the grocery store. That’s the second point, if you don’t absolutely need a large truck for business, you shouldn’t use one for your everyday driver. Imagine if big rigs were affordable for most everyone and people used them for daily driving.
While I agree that farmers can have specialized vehicles for different tasks, not all do. We farm sheep, pigs, chickens, and ducks and do not have specialized equipment. We don’t even have a tractor. I also don’t disagree that people who don’t have a use for trucks don’t need them, but I wouldn’t go to far as to say they shouldn’t have them. While objectively worse for the environment than a vehicle more suitable to their lifestyles, it’s a slippery slope (as we’ve seen) once we start legislating morality.
Bottom line: if we didn’t operate a farm business, we wouldn’t have a need for or the desire to have a large truck. More likely, any truck at all. We certainly wouldn’t have one to park in the driveway of the suburban house we would probably live in. It’s just impractical, but not everyone is gifted with innate pragmatism.
