Because most commercial applications want accuracy and scale. So use structured light, background target grids or multiple fixed cameras. This technique needs fairly simple shapes and assumes that edges are square etc. You couldn't use it to scan a clay model for CGI or a complex shape for cad. You can use it to convert simple 3D objects into CAD but that's a bit pointless compared to just drawing them in CAD. It's clever, congratulations to Mr Pan, but it's not as earth shattering as the press releases claim.
