My sentences is maybe badly turned, didn't mean to portray him as a bad guy. More like a mad scientist  haha

Magic tools are the closest thing this world has to electrical appliances. Their use is limited because they have to be created one by one by hand which is partially why they're so expensive. So a lot of the trade of magic tools occurs at a national level between nations, organisations and world-leaders. That's the status-quo.
What the prince is basically trying to do is the equivalent of creating a machine for cheap mass-production for every kind of magic tools. For example instead of only royalty have AC in few rooms, with a bestowal magic tool everyone (rich enough) can get it, in many rooms. So modern technology is now widely available (relatively). This will revolutionise the world. And his Kingdom will have sole monopoly over it. Ergo World Domination
