Is selling shares in yourself the way of the future?

Imagine having to work your ass off to buy back shares in yourself to have a majority and be back in control of your own life.

This is basically the plot of /The Unincorporated Man/ (Dani and Eytan Kollin, 2009), except that the protagonist (a freshly thawed man who was a billionaire in his own time) refuses to incorporate. It's all very Heinleinian, but without the horny, nerdy redheads.
