Because it is analog. There are no buffers or anything in between. Your PC sends the image data in analog throug VGA pixel by pixel. These pixels are projected instantly in the requested color on the screen.
And no motion blur because the image is not persistent. LCDs have to change their current image to the new one. The old image stays until it’s replaced. CRTs draw their image line by line and only the the last few lines are actually on screen at any time. It just happens so fast, that, to the human eye, the image looks complete. Although CRTs usually do have noticeable flicker, while LCDs usually do not.
