it works like this. In a free market, you dont have to buy my services, but you will if it is better for you on the whole than not. I may consider you cattle to be exploited for profit, but you probably wont just give me your money if i try to sell you my grass offcuttings for $10k. If i somehow come up with a way to produce a great lawnmower that costs me $1 to make, and I sell it to you for $100, you would perhaps think this is a great thing, while I make out like a troll. win/win. If I offer you a shitty lawnmower for $100k, you simply decline.
