There's no master plan, it's just that technology is making life more efficient, and more productive. It's also the downside of freedom: you're free to make bad choices too.

Should we ban cars to force people to hike uphill to work? It would mean people would have to live in smaller apartments in cities, and the workforce would have less talent. But we could do it.

Should we ban rich foods in the mall? Do we want to live in a world where the government forces healthy choices on people? Many would argue the downsides outweigh the benefits, and most of us live in democracies.

Society is not obligated to make the choices you want to make easier for you. That will never change, so you might as well focus on yourself and your own habits.
