  De Broglie–Bohm theory does not have local hidden variables, it has global hidden variables. The difference is quite fundamental. Paper falling is influenced by local hidden variables, because all interactions are described by Euler-Lagrange equations which being differential equations are by their very nature local. Global hidden variables are no different than modelling quantum mechanics on a computer (using traditional quantum field theory) and saying that the seed you use for your random number generator value is a global hidden variable. There's nothing deep in that.
