Your neck is intact. Indeed, Tesla did use simple DC resistance (he
had no knowledge of skin effect or other losses) to calculate Q. This
lead to some whopping Q factors which he then used to calculate the
performance of proposed wireless power transmission systems. Draw your
own conclusions from there.
