The point of the stock isn't selling it for cash, it's having a share in the profits and more importantly voting rights at the company level. Are plenty of people "happy" being wage labor? Maybe. Certainly compared to some of the alternatives - unemployment, welfare, homelessness, lack of health care access. Is it really anyone's heart's desire to sell their labor for a paycheck, though?

Start a business... I've thought about it. If only it were so easy. Even if I did, that solves the problem for me, but not anyone else.
