To be fair, some of this was common sense. Since Turnamancy is required to give the motion aspect to objects, logically it follows that boats, which are not alive, must be manned or enchanted.
Like, say your florist makes... Oh, a pumpkin carriage. In order for it to move, a turnamancer would need to do some work on it, at which point it becomes a magic item with some mount properties (and since you're riding inside the pumpkin, a defensive bonus XD). Hippymancy doesn't include Motion as an element, see?
So maybe creating boats, which are made of wood, is a natural form of flower power.
I think shackles might be too... I mean, they prevent one from attacking, right?
UNLESS someone like you cares a whole awful lot, nothing is going to get better. It's not.
