The point of the Silver test is that newer players may simply ignore Silver as an option.
That may be the point to you, but it was not the point to the person who coined the term or the people who then advocated it. Their point was, actions suck, why are you buying actions, this game is stupid.
New players often fail to buy enough money, including Silver, but that has nothing to do with "the Silver Test."
I think every player has a similar learning curve:
Lvl 1: Buy at least one of each action card just to see "what it does".
Lvl 2: Buy a limited number of action cards, but still way too much and have terminal collision each hand
Lvl 3: Action cards didn't help much, switch to just money (with the occasional action card), beat other players stuck at lvl 1 or lvl 2
At this point a lot of players think they have "solved" Dominion and they just stop. As they are already the best players of their limited group, there is no reason for them to evolve or for the group to evolve as a whole. It actually takes some imagination and skill to go to the next level.
Lvl 4: Vary action cards and money cards, know how to build an engine that can beat lvl 3
Lvl 5: Optimize your engine, get the cards 1 or 2 turns sooner than lvl 4 players, also have a better understanding when to keep it simple
