Wireless charging can be surprisingly efficient.

(It’s been a long time since I watched it so I might not remember the details right.) In the end it doesn’t have to be exactly as efficient as wired charging, and probably never will be for a good implementation of a wired charger. It only has to be so close that you don’t care about the difference. I don’t think the inverse square law is very relevant on these scales. Electromagnetic radiation can be focused.
