@chibit: Thanks for clearing this up. So they could sell his products, that he can mass produce, like simple antibiotics, clean bandages and effective potions made from herbs, but this would mean for the guild to get dependent on the MC, while partially letting go of their old supply lines, which in turn at this moment are owned by some of the wealthier guild farts, I'm sure. The patient peace of mind, placebo effect, is nice and dandy and it does help in some cases, but selling the dream to get healthy again, when one has a sickness, that can't be cured by the body without an effective medicine, now that's no good. Even more if you do everything to disturb new technologies so your old business model continues, instead of looking into the new ways. Thinks shouldn't be rushed (as only we and the MC know, that his tech is working), but it should be at least verified.
Now we do have an interesting case here. Should we either
1. let a thriving medicine distributing industry, that distributes only half ways effective medicine, but
DOES deliver, suffer damage by new technologies (this might mean that some people are cut off medicine for some time, effective or not, and might die) or
2. let that industry slow down this development, to gain time to adept, but in the meantime people, who could only be cured by the new medicine, are suffering and dying.
The best scenario would be no 2, with the guild adapting the new tech asap and in the meantime opening an experimental clinic. But that guild does not want to adept the new ways, as they fear it will lower their (personal) income. People will die either way, but in the first scenario the queen could step in and authorise an emergency medicine distribution program of the cheapest medicine, which would be MC's, to the poorest to lower the mortality rate. As a result the mortality rate would be lower than before and afterwards the new ways would have been established, lowering it further. And a lower mortality means a healthier economy, means more tax money. A dime wisely spend. Also, if the guild is forced to, it will react by adapting. Businesses fight and adapt, so they don't go out of business. They aren't that weak.
