We're illustrating how ridiculous your claim that "guilds have always been able to declare what vendors create for them" is

Now you're talking about government regulations for some reason. Even your examples of customers being able to compel production are actually examples of governments being able to compel production, and in just a few of these scenarios the government is the customer. But it's their power as governments, not their power as customers that can compel production.

As stated: you've lost the thread. You're talking about totally irrelevant stuff.
