Soccer and Video technology

We are living in the age where you can view yourself using your computer through the lens of a satellite hovering above you. Yet, simple video replay and goal line technology just scare the shit out of the soccer community. In a 90 plus minutes game, offering a few seconds for the referee to get a confirmation from another trained official sitting infront of a screen with replay capability isn't too much to ask for, is it? With that, no one can argue about stupid decision because there won't be. Won't the quality of game play improve because the players don't need to waste effort trying to argue with referee? Secretly, I believe a few second delay for each important decision will actually allow the more game time in the 90 min because players will spend less time debating with the referee.

So what's stopping video technology from being adopted? IMHO, the are:

1) bad refereeing is absolutely necessary for bookies to win money

2) they are afraid of changes

3) they secretly wish referees suffer unnecessary distress from making bad decision and fan abusing them.

Actually after typing them out, I only believe in no. 1.
