The case for living and working in space

Earth's massive gravity well makes it near on impossible to send cargo into space at an affordable price. Thanks to Elon Musk that price has dropped thanks to reusable rocketry. It'd still expensive to haul infrastructure up into orbit but it's getting cheaper making the establishment of a moon base a realistic proposition. With one sixth the gravity the moon has a major advantage over the Earth. Rockets can reach orbit using far less fuel and solar energy can be utilized without atmosphere diluting energy flow. But what if we had virtually no gravity to contend with. In such an micro gravity environment energy required for transport would be minimal and heavy objects have no weight. Massive structures could be build providing customized artificial gravity for people living and working there. Enormous space ships could also be constructed designed to only operate in micro gravity shuttling between space habitats, asteroids and orbiting planets. Initially there would be huge start up costs before a space economy hit critical mass but once it becomes self sustaining mass production will reach such a scale that it will make Henry Ford's head spin.
