Wouldn't solve the problem.
If Steam republished all its now censored games, and magically developed and implemented a world class crypto payment system overnight...
Then Steam is still in breach of MC/Visas terms, and MC and Visa drop them, and now everyone has no choice other than to use GabeBucks or w/e to purchase Steam games with.
Also, Valve now pays employees and game publishers in GabeBucks.
Which would cause a fuck ton of games to leave Steam.
=D
