You're thinking of the inverse square law the wrong way. What it means is that at a distance, d, the power from the source is distributed over an area proportional to d^2. Hence, if you double distance, your power is distributed over an area 4 times as large. However, if your receiver still covers the whole area, there is (in theory) no power lost. Ideally, what you have is parallel rays transmitting the power, which would imply the area doesn't actually increase at all as distance increases
