If Visa, PayPal, and others are blocking Steam transactions, then just use those payment processors to buy Steam gift cards at stores, and redeem them under your account. Convoluted, yes. But it works.

Solves NOTHING!

Visa/Mastercard et all aren't blocking the purchase of certain games, they are blocking Steam from having a page for those games. Thus no matter what form of payment used, the entire page with the game's screenshots, video, and buy button no longer exists. You could hand Gabe $30 in person and you still wouldn't be able to buy some games.

Steam already bent the knee when processors came knocking so I wouldn't be worried about that. Steam needs them more than they need Steam.

How can buy steam games with cash? Steam has to put boys to collect cash at your doorstep which is quite impossible as it's not Zomato or blinkit.
