What need does the tobacco industry serve that was not created through addiction and marketing? The oil industry knows about the damage they've been doing to the planet for decades. But not only they ramped up production but also lobbied hard against any form of regulation that might affect their business. The result of this is not that we have a need for it, but dependence. People work to be able to give themselves and their families a good life, everyone wants to be happy. That's it, what other justification is needed? Most of these industries might have been born from a need but their whole goal as they develop is to get society to depend on them so that the need is not covered by better (less impactful) industries.
