I think the whole point is that those weapons/armors aren't supposed to be borderline trivial to get. Within like a couple of weeks I was up to the 10s of thousands of denars just from trading, then went around buying enterprises and got a ridiculous amount of money, if it hadn't been patched I could have kitted everyone out in solid gold everything by now.
200/day isn't really that bad, it's still 5600/month and you can have up to 4 IIRC, so you can comfortably keep a fairly large elite stack of troops under you and have denars left over to invest in trading or whatever else.
