I hate to say this, but take a look at Rebels for this.
There's a bonafied jedi in that and they're still stealing stuff from the empire and selling it to arms dealers and stuff.
The "I own nothing" type jedi were back in the day when jedi were a "sect" with influence and holdings. Where their members didn't have to go starving and alwaysh ad access to ships and anything else they could need.
A force sensetive (or jedi, if you will) in EotE will have to get money for themselves. They'll have to do shady things.
But they don't have to do evil things.
That's the difference.
Stealing from a corrupt and evil organization to sell to someone in need (at a greatly discounted price, of course) is not exactly a bad thing to do.
And since they're stealing the stuff, it's all 100% profit. So it doesn't matter if they sell it cheap.
They aren't sitting on a million credits in Rebels....
I think that was part of his point, hence the "greatly discounted" line. You're stealing from the Empire/crime syndicates and giving it cheaply to those in need for whatever meager credits you can get for gas and food. As the GM, I'd always have whatever those poor refugees offer be just enough cash to cover expenses, and maybe partially paid in barter goods that the PCs then have to go sell in the NEXT system over, and...well, you get the idea.
I don't really see anywhere that he said they should have a million credits, just that they should be allowed to have the means (a ship, some supplies) to go out and earn their small income stream. In fact, I'm really unsure where the disagreement is if you both agree that Rebels is a good model for Jedi not being completely poor, just MOSTLY poor.
Well, they could just sell stolen imperial weapons to the rebels. They have funds.
Sure, they won't become millionairs, but they'd get more than giving to starving refugees.
OR, they could actually sell the stolen stuff to independent systems, shady corporations or even criminals.
