How’s this for a great idea: we build a small fleet of cars, and market them to people in the local community. How do we compete with Ford, G.M., Toyota, and all those other huge car companies? Easy.
You see, our cars will have special octane requirements that will prevent them from refilling at ordinary gas stations. Instead, we’ll set up a few local stations that will be the only ones equipped with the right fuel. To top it off (so to speak), our cars will also have small gas tanks to prevent them from reaching the next town on a single tank. (Should we decide to go electric, we can instead equip them with special plugs and voltage requirements to accomplish the same result.)



What all this means is that unlike other cars ours—call them “LETS” for “Local Energy Transportation Systems”—can only be used around town. That way, people who go shopping with them have no choice but to shop locally, and so contribute to boosting the local economy. Who wouldn’t want to do that?
The answer, to get serious, is plenty of people wouldn’t. Even people who like to buy local don’t like having to do so; and the option of driving out of town, whether to shop or for some other reason, is valuable. So a car that can go anywhere is worth more—for many a lot more—than one that can’t, which means that so long as Ford or Toyota or any other manufacturer can make a decent “national” car for no less than what the local alternative would cost, we’d better leave making cars to them.
Such reasoning presumably explains why there’s no such thing as a Local Energy Transportation System aimed at challenging existing car makers. Yet there is such a thing as LETS: it stands for “Local Exchange Trading System,” and there are now several hundred such systems in operation around the world. LETS are part of a still larger “local currency” movement.
