You can’t plant a pie and grow two pies, and in fact it will go bad quickly, but you might be able to trade the pie for seeds, grow them, and reap enough to trade for two pies. If no one with seeds wants a pie, you might have to make a chain of trades, e.g.trade the pie to the cobbler for shoes and trade the shoes for seeds.
Even if you don’t want to grow seeds yourself, you might trade the pie for farm tools, then trade those to the farmer in exchange for seeds at harvest, then trade the seeds for more pies.
Now it’s not guaranteed that these sets of trades are possible. It could turn out that the best deals you can get will leave you with half a pie at the end. But usually, if some goods can be used to make more goods, and baking pies isn’t going to get any harder in the future, exchanging pie today for pie tomorrow will get you more pie.
Money and financial institutions abstract trade chains away, so you can sell your pie, put the money in the bank, they’ll make loans to people who can pay back more in the future, pay you interest, and then you can buy more pie. The interest isn’t a distortion caused by money; it reflects a possible set of trades that might not be obvious but would be possible. If such a set of trades doesn’t exist, you won’t have positive real interest (real interest is the published interest rate minus inflation).
If you give all of the upside of the loan to RC there’s nothing left for the stranger and no reason for him to bother. If they’re able to negotiate an interest rate, they’ll find a deal that works for both of them. An equity arrangement where RC gets a defined percentage of the stranger’s harvest instead of a fixed amount of grain is also something they could negotiate in traditional capitalism, if such a deal were preferable to both parties.
