It may help to know that while journeyman and journey come from the same French word, journée (meaning, essentially, day), that journeyman simply means someone who is entitled to charge a day rate for his work. (Masters were the "contractors" of their day; they were paid for the project, and apprentices got to eat -- they usually paid for the privilege.)

Yes, the guild system and town laws often made the journeyman itinerant, but it wasn't travel that put the "journey" in "journeyman".
