I'm really not sure what the strongest possible interpretation of "lets go back to before the industrial revolution" is other than 90% of people being subsistence farmers on the verge of starving. People moved to cities because less agricultural labor was needed and people living close together makes them more productive.

People moved to cities because more industrial labor was needed. Proximity made industries more productive. Now more digital labor is needed. And people living far apart can be highly productive.
