Why is the Crown Theocracy so obsessed with igniters?

Why is the Crown Theocracy obsessed with promoting the distribution of igniters? I know Sanctism hates everything the World Before including its magic and wishes to suppress it, but why promote any magic at all even if muzzled by technology? Igniters play such a large role that one of the five Senators is the Igniter Consortium head. I just finished the game last night and I'm not unconvinced that Sanctism and its bigotry against all things the World Before was just a tool to sell igniters as a luxury good.
