Worker ownership is not the same thing as wage labor. Wage labor bifurcates people into an asset owning class and laborers who don't own the assets they're forced to depend on to eat. Wage labor divorces workers from owning the fruit of their labor in place of wages, whereas worker ownership doesn't.
Wage labor was imposed upon people hundreds of years ago with the enclosure and privatization of common lands that people had relied on for centuries to provide for themselves. It was imposed because people voluntarily chose not to become wage laborers, as they preferred their lifestyles as is. To rectify this, a landless class of people was created, that could only rely on selling their labor to survive, through the enclosure of the land they had relied on in the past. People did not freely accept becoming factory workers, for example, they were forced into situations where it was the only option, and in many places, those that chose not to work were arrested and forced to work anyway.
Worker ownership is at least a respectable alternative. But it has a problem with capital-intensive industries. The workers typically don't have the resources to pool their funds and build a semiconductor fab.
