Ah, but I’d argue that you are playing that game, because it’s just incredibly basic supply and demand. So whether you have a job or provide jobs or own or rent or buy things at the store or sell things online, you’re playing this game too. And you only get to play your side because someone else plays the other side. Seems pretty morally incongruent to call them irredeemable for voluntarily selling or buying from you, doesn’t it?
Edit: for example, if you’ve rented or bought, you’ve contributed to the demand that makes the market price go up. If you were a landlord, at least you’d be helping provide supply that keeps the price in check :)
