1Q: innovation, competition and profit motivation.
2Q: freedom, and voluntary exchange and trade
Q2: voluntary exchange and trade: The words "exchange" and "trade" refer to the same activity-people who have one thing and want a different thing can exchange or trade it voluntarily with each other. The word "exchange" tends to emphasize trades within a single country or locale. The world "trade" tends to emphasize international aspects. Regardless, the activity of exchanging or trading is the same, whether it is with your neighbor or someone living clear across the world.
Freedom: is being unopposed in regard to your own life and property. (Presuming, of course, that you don’t intrude upon anyone else.) What if you want to allow people to smoke in your restaurant in a major US city? If you do, your money will be stolen from you by the government. If you hide your money from them and keep doing it, they’ll send armed men, seize you, and lock you in a cage. Are you free? After all, this is your own property we’re talking about. Why can’t you use it how you wish? You’re not forcing anyone to come inside after all.
