There’s an old saying that there are only two things in all the worlds that can’t be escaped.  Death and taxes.  That’s not entirely true anymore.  You see, starships are recognized as sovereign States, beholden to no government.  We fly where we want, land where we want, and do what we want.  And my ship is a tax free zone.  Of course, we do avoid worlds with heavy landing fees.  No sense in draining the national treasury on the stuck up ones after all.
