Put simply, future value. Otherwise a sidewalk lemonade stand profiting 1 cent per glass would be far more valuable than a lemonade manufacturing business which sells millions of bottles a day and pumps all the profits plus additional investment money into manufacturing facilities. At some point, the money-losing lemonade manufacturer no longer needs to ramp up their facilities, they pay down the equipment cost, and generate boatloads of profit. That or they get bought out by a larger player who wants to enter the lemonade market but doesn't want to reinvent the wheel.
