Yep, company dorms, company stores, etc. have been tried before. We've made labor rules prohibiting them because we realized that the line between dependence and outright slavery blurs more quickly than many expect. It's a trap.

Sadly, this gung-ho "for the company" attitude, which arises from a combination of naivety and boredom, is one of the essential characteristics that VCs want to see in prospective founders. It's one of the biggest reasons they push the "You must be young and pure to be an innovative founder!" angle, although most people aged 25+ can see pretty clearly that experienced founders would be a great benefit to any company. That experience threatens the VC game, so they keep it as far away as they can.
