I don't find the game "confusing" although there is a learning curve especially when it comes to the controls of the ship. But this learning curve and complexity is not more than for, say, a flight simulator or a rather involved RPG. (In fact, flying a plane from A to B in FSX or X-Plane and landing successfully would be far more difficult than it is here to get from one system to another).
I think the learning curve required to get started with the game is "just right".
A tutorial at this point doesn't make a lot of sense. It's a BETA in development. We are testing a game and whatever this implies, eg having to learn the game incl. the quirks. If you want a tutorial, manual etc. you should wait for release.
This, fortunately, is not a game that you buy and in two days you are as effective as it can get, be it as a trader or pirate or whatever. In the same way as you ALSO cannot sign-up as a newbie to a game like WoW and expect being a master at your class in two days. Then, the game is also NOT that complex that achieving things relatively early would be impossible. In fact, it is actually really simple as soon as you understand how to fly a ship.
