If people are isolated and don’t have social support and are therefore more emotionally vulnerable and unstable (basically we are put into isolation to a lesser degree than prison inmates) then it is easier for the government to control us.
Why do you believe the government seeks to control us? Genuine question
Not OP. I don't think they actively want it or pursue it as some sort of conscious objective, it's just something that makes a lot of things easier for government. It's essentially gradient descent and the government following the thing that's slightly better for it, with no view of the bigger picture.
The government has laws that it makes you obey. American Values they want you to have. Money of yours that they take. How is it different from control?
