The point isn't that life meant never having to work. To make a stylized sketch of it: life, or identity, is increasingly made more legible to the State. Legibility of information is the backbone of state power(1), moreso than even violence or popular support. Legibility of identity is therefore granting the state more power over the individual, which further undermines human autonomy by making the ability to live dependent on remaining in the good graces of the State, by paying our dues and contenting ourselves within the all-encompassing social system that develops.
