Well first of all, you didn't even answer how you'd stop the kick. I doubt you even know the mechanics of it.
Second, let me give you a hypothetical situation. A group of boys want to become a basketball team. They practice dilligently, but never play against another team, much less professionals. They never learn opposing strategies, or how to counter them, because they're never faced with coaches and players that have different thoughts and ideas. After several years, they're thrown in court vs. the Lakers. The lakers have refined training, strategy, conditioning, skill, all versus opponents of varying skill levels. They've been in real games and tournaments more than anyone can count, vs. real players, who think, adjust, and counter as well.
Which team wins? If you never get in a real match with someone of real talent, you'll get eaten alive vs. those that have been there. This has been proven time and again.
