Couldn't phased arrays ensure that everywhere (within region) but the target gets only a small amount of power?

  In theory, yes, but practice no. The antenna required to collimate the beam from LEO, down to a person sized spot on earth, would be massive. Single antenna apertures are limited to about 90 dB of gain, and I doubt that is near enough, but I’d have to run some calculations.
