How's that? I mean he still needs to eat just like everyone else, and it's probably been very easy work so far for a person of his talents and flexible morality. Don't forget; Ronin were a real thing for a reason. Samurai were nobles with exactly one skillset, which means 1) they needed a patron or employer to be able to feed themselves, and 2) they were accustomed to a certain type of lifestyle. When their Shogun got knocked off, that left them actively hunting for work.
Baylan (or any Force user without ethics) doesn't need to work to feed himself. He throws the chance cube, it comes up the way he wants, and endless variations on that theme. You use the Jedi mind trick to get the bank teller to hand you that big stack of credits, no questions asked. You do the same to get some Han Solo wannabe to hand over the title and codes to his ship.
Baylan has no worries about where his next meal is coming from. In that sense, working as a mercenary is pointless.
Also, we don't know what his actual motivations and long term plans are here, but from what he said in the previous episode, he believes this quest will lead him and his apprentice to some kind of vast power.
This much is true. Given his sort of melancholy and half-participation so far (his apprentice carries most of the 'work' so far), it'll be interesting to see where he stacks up in the final tally, so to speak.
