Can we could build a miniature liquid fluoride thorium reactor instead?

I'm pretty sure that the smallest designs for nuclear electricity systems produce far more power than is needed for a commune and cost far too much. Even if the cost per kilo-watt is one tenth as much, if you have a small community of people who are attempting to get by without working, you probably can't service the higher capital costs. Please don't let being cool get in the way of being practical.
