Therefore, pressure from the Rebellion would mean nothing!

I didn't mean diplomatic pressure, I mean "aggressive negotiation" type pressure. Think of the scene where Leia enters while everyone is sleeping, I imagine that, only a squad of about 10 or 15 guys with big guns who, once everyone wakes up and realizes what is going on, start blasting through pounds of alien flesh on their way to Jabba's beautiful commemorative Han Solo collector's idem. Luke could have gone with them just for fun so he could knock people around with his lightsabre.
