I agree that it's the distinction between legitimate and illegitimate authority that's the key point. Robin Hood is one good example. Another is the Dukes of Hazzard, which is what I loosely based a current PC on. (More the early seasons when they're dealing with real crimes like car thieves and record bootleggers, less the later slapstick episodes like the great Christmas tree heist.) The Duke boys are honorable, help those in need, see that criminals get punished, and respect legitimate authority by helping out the FBI or honest cops. It's the illegitimate authority of Boss Hog and Roscoe that they ignore.
Under similar circumstances I could easily see a Paladin working with an honorable thieves' guild. Part of the Code is to punish those who harm and threaten innocents. If the guild's activities can be fit under that heading, and the local authorities are illegitimate in the Paladin's eyes, then it shouldn't be a problem. Especially if the guild then turns around and uses their gains to help those in need. Honorable might just mean that they make sure no bystanders are injured or robbed.
