The theory is simple. Instead of formal concentration camps, you herd people into cities, which can be contained in multiple ways. As in China with its lockdowns, you put the people in massive apartment buildings which you can lock up. Once you install social credit systems, you can control money, ability to pay rent, buy food, drive a car, rent communications services. And you bind people to a welfare system while also removing small business and jobs.

I think this is why the WEF is trying to get rid of farmers and rural dwellers too. The long-term plan is to pack the population into controlled areas and remove independents who could be self-sufficient. This is why the covid lockdown plans tried to destroy small businesses. Which they did.

By taking away gas engine vehicles you keep people bound to the grid and less able to escape. Instead of people going somewhere for vacations, they are forced to use VR once confined to stay in their rooms. Zuckerberg is a tool that for that future.

Also, once people are concentrated in cities it is easy to introduce new plagues and kill them off more quickly.
