I have no idea how in the world you think that could ever work in a general sense.

Things require labor. Labor costs money. Ergo, people giving you stuff require money, somehow. A tetris clone requires so little labour, that a well-off person with too much time (ergo labor) on their hands can give you that for free, but that's not scalable for 99% of important stuff.

Because capitalism, they also require more money, YoY, than last year, meaning they can't just make a steady stream of profit. They need more profit every year.
