It’s not a false dichotomy at all. There is a finite set of resources that can be deployed at any given time. $1 spent on a laptop is $1 that isn’t going to medicine. This usually a curve rather than a straight line (so usually you’re better off with some combination of both), but this doesn’t really apply to a situation where your limiting factor is dollars rather than the factors of production.
