That is where other players who can actually afford to own their cards come in. Some people play differently. We can't make the extremes as a premise for an argument.
Tho, I agree with you that win-traders should be banned, the proposal to exclude non-CP owning players from rewards only favors those who are either OG to the game or who can spend thousands of $$$ to actually own their deck.
The real solution is here is to GIT GUD. Just because someone can shell out money to buy cards doesn't mean they are only ones who deserve to win and compete.
