No, it requires far more work because you're doing everything by yourself at first. At his current workplace, there are people for everything - few for IT problems, few to interact with and help customers, few to do finance stuff, few for lawyering, and etc. If thornles is his own man, then he'll have to do all of that until or unless he hires more people. It takes far more work, and you're less likely to break even when you start out unless you already have the equipment, location, and/or clients.
Being an entrepreneur is a very hard work, especially with the amount of risks one would have to take.
