The people enjoying it, I guess xD.
For a slightly more serious answer, many systems have a neutral trade hub that you can a) trade at and b) for a onetime fee, use as item storage/ship production. You should also pick your starting faction (and starting system) carefully-- some factions have relatively easy starting systems (near the center of the map, easy hostiles, etc) while others are more of a challenge.
While you don't get credits from battle, you do get heaps of electronics. Sell those; they're required to produce ships but generally not in large amounts. Since you
cannot self-sustain yourself in terms of supplies/fuel from loot, you have to plan your sorties accordingly. Additionally, having a good amount of freight to supply your fleet is now very important.
I'd say US:J is meant for a slower-paced, more methodical/strategic approach than most other mods (though not all, see: Ironclads). If you're looking for just the battle side of things, there are plenty of other fish in the sea.
