I understoon the Bronze Lake quests were initially added to reference the 1.0 Hildy quests, in which Godbert was still in mourning over losing his son during the Calamity. (Our helping him get out of this funk is why he gifts us a Meteor Survivor Ring, as it has a good deal of symbolism for the old man.) Also, there is simply nothing in the game that indicates Godbert is a Royalist, nor that being a monetarist=evil, avarice fueled monster as we've seen with Taleji.

Though, the only other Monetarist we've spoken to is Dewlala, leader of the Church of Nald'Thal, which, as a religious order, puts intense importancy on personal wealth and incredibly high tithes. We don't even know if she's on the Syndicate as a representative of Nald'Thal the holy body, or if her personal wealth as the church's leader gives her enough money to qualify.

But, she was absolutely in cahoots with Lolorito in regards to halting Nanamo's plan to force complete governmental reform. Her being the city's major religious leader puts her in an odd position, as she could rightly argue her siding with keeping the status quo was to prevent unneeded suffering to the masses. I'll need to rewatch the cutscenes from that point in the story, but I do remember she almost chastised the WoL in the scene.

Back to Godbert, he does employ hundreds of people from all corners and walks of life, and he donates a few million to the Starlight Festivals. So it's really impossible to know yet if his choice to bar the Domans was a Monetarist power play or him being so uninvested, he just walled put when everyone else did.
