Exactly.
I worked on a huge project to beam power into the body, wirelessly, for an implanted blood pump /artificial heart.
It works for small amounts of power, like for pacemakers or nerve stimulators. But for any kind of real power, the power needed to move motors and do real work, it's just not feasible.
No matter what fancy math or physics you do, no matter if you work with a fancy tech firm that has decades of IP in this field and was founded to make this technology specifically (like wiitricity). None of those things changes the fundamental underlying physics. Energy in the EM spectrum decreases with the square of the distance, period.
If you need to beam a tenth of a watt one foot, that's possible, if you want to beam 10 watts 2 or 3 feet, that's possible (both with very large losses, 50% or more). Anything beyond this in distance or power is just wasting energy. It's like heating up 500 gallons of water, carrying it one mile and using the last 2 degrees of delta temperature left to do something. Instead it's far smarter to just take the 50 gallons of fuel one mile, heat the water there, and use its full energy.
