Not quite, the fact that half the lines are missing is partly true. If you were to compare a 240p to a 480i signal, it would be true that half the lines are 'missing', since 240p has half the vertical resolution of 480i.

Scanlines have nothing to do with "The time" it takes for the electron gun to move back to the (usually) left side of the display. We can move the electron beam around at nearly the speed of light, and it's flying across the screen at about 15,750 thousand times a second.

Scanlines are simply the absence of video data. The black lines are nothing more than undrawn phosphor. Since the electron beam only illuminates a section so tall, you end up with lines between the video data. The higher the resolution, the more lines of video data, and the smaller the scanlines get. Bigger screens get bigger scanlines, smaller screens get smaller scanlines.
Scanlines are nothing more than a video artifact.

Interlaced video exists more out of the necessity to fit more resolution in a finite amount of bandwidth.
