RE: Laissez-Faire Leadership - Let us do!
I agree with your idea, while I'm not so sure about the name of your aproach.
I study economics and Laissez-Faire Leadership is defined as completely hands off. So not only giving people autonomy to find solutions for their problems but not showing any interest at all. No motivation, not disciplin, almost no feedback at all.
The most recommended style of leadership is called stewardship. Where you give the people you lead autonomy and trust, while sharing your ideas and philosophy.
It's more complicated than that, but I think what you are describing sounds a lot like Stewardship.
