The questions basically asks if it is possible for an individual to save and invest in a corporation without lending money to it or purchasing additional shares?

I would assume there would be no way of investing in a company if you don't have anything TO invest?
SO how would not lending money or purchasing shares classify as the individual saving and investing?

Am I way off on this?

If you already owned shares, you could have the dividends purchase new shares each year instead of paying out in cash, and thus you invest into it every year without actually paying out money.
