If you want to drag a file and move it you hold down option to change the copy into a move; if you want to paste a file and move it, you also hold down option to change the copy into a move.

FWIW, I used Windows for a LONG time before begrudgingly having to use a Mac for my development work, as I was doing iOS development and no one else was putting up with my I-will-claim-perfectly-reasonable alternative Linux toolchain... and Mac's keyboard shortcuts are so much more consistent that when I went back to using Windows it was the one thing I seriously missed. Hell: Mac OS even has Emacs-style cursor commands available in pretty much all native controls... Linux doesn't even have that (I'm using Linux right now and am still sad it isn't like Mac, and I had also been using Linux since I was a kid).
