There's nothing wrong with wanting to make a budweiser clone. If that's what you like, you should try to brew it.
However, having said that, a few more things need to be said:
(1) brewing a light american lager can be tricky. The flavor is delicate (some might say non-existant), and ANY imperfection will stick out like a sore thumb. It's also crystal clear stuff, and that's kind of hard to get with homebrew (they have very expensive filtering equipment and we don't.) A.Busch's brewing method is VERY refined and precise.
(2) after you drink several batches of your "amateur tripe" you will VERY likely find that you enjoy it very much. You might also find that you have trouble tasting american lagers (they will seem very watery). Even a light-bodied, simple ale will pack a much bigger flavor punch than budweiser. Don't be surprised if, by the time you feel skilled enough to try a budweiser clone, you find yourself no longer calling that style of beer your favorite.
Brew on. If you want Bud, brew it.
