[Star Trek]I'm a human being living on Earth, and my dream is to command my own spaceship that isn't owned by the Federation, but I live in a post-scarcity society with no concept of money. How do I go about acquiring one?

I find it difficult to believe that I could simply replicate all the components and have some sort of automated system assemble them, but could I do just that?  Or would a human have to go about another process to acquire things that humans from a less civilized age would associate with great wealth?

What you described was actually done by Benjamin Sisko and his son, Jake.  The two of them undertook a father-son project in which they built a Bajoran lightship and flew it through space.

Please bear in mind that the Bajoran lightship is a small vessel whose design is centuries old.  If the Enterprise is like a modern day battleship, a Bajoran lightship is like a schooner.  Sisko and his son were able to build the lightship more-or-less on their own.  They had no apparent issue getting the building materials, and the construction was apparently easy since it was a two-man job.  

No one on Deep Space Nine attempted to stop them, which suggested there were no legal obstacles to constructing a personal spacecraft.  

In the end, the two of them flew from DS9 to Cardassian space, where warships intercepted them.  If they hadn't flown into Cardassian territory (and if they hadn't encountered critical technical difficulties along the way), their space voyage would have been unhindered.

Building and owning a relatively simple space-capable vessel is definitely feasible. Building something as large and lethal as a Starfleet capital ship is far more complicated, however, and will undoubtedly attract the wrong kind of attention from Federation authorities.
