Hmm...but you have to begin somewhere. You do not have to show hostility against others if you don't have the fitting ID. My suggestion would be to get the Zoner ID or the Freelancer ID.
With a Freelancer ID you really can be neutral to almost everyone, even the Gallic House I think. But like you said there is a cargo capacity restriction. If you want to stay classic and visit the non-Gallic space only then I would suggest a Zoner ID because there is no cargo capacity restriction.
Keep in mind that only the best factions on the Server get their own ID's, like the Hellfire Legion or the Reapers of Sirius. You would have to walk a long way with a different ID before you could get your own.
But all in all the introduction is not bad. Have read worse.;)
