The intuitive issue with that is as follows: For any smooth compactly supported function [math]f[/math], it's support is inside a compact set [math]K[/math], and this compact set is covered by [math]supp ~ f_i[/math]. Take a finite subcovering and torsion your way into getting a partition of unity out of the finitely [math]f_i[/math].
