They aren't as important as you think.
They are one of the cool things that you can do, including pyrokinesis, telekinesis, electrokinesis... but they're just cool things, not important things. Some people have to start with the cool stuff before they realise the important stuff, though. If a lot of new Souls have been born, then they would be immature in some ways, so coolness is somewhat important.
