Is the "Inspired Creation" spell talking about rules that don't even exist?

Think about it; in many, if not most, fantasy RPG settings, the populace is better fed, healthier, has more readily available metal weapons, armor, and other tools, is better educated, further traveled, and so on, than in any comparable medieval or early Renaissance locale. It's sometimes enough to make the setting seem like a Ren Fest version of itself. Far from being a problem, I find that assuming widespread use of 'utility' spells actually serves to justify these aspects of the setting.

You might want to set certain limits, such as only letting wizards create metals from earth and stone that are already present in ore form, at least in trace amounts.

I agree very much and its been my approach.
And spells that I dont like the potential effects are either banned or secret. Just because its in a GURPS book doesnt mean you have to have it in your campaign.
