It's not about paying Google. People can buy gift cards with cash and do that; that's not the problem, especially not for commercial use. It's everything else that they're imposing or could impose on a whim and whose device it is they're putting restrictions on.
Last I heard, Google doesn't employ law enforcement. I can auth to the people we vote for and any laws they make such as bank KYC against specific criminal activity. Nobody gets scammed via an apk when it's infinitely easier to put up a webpage or socialmedia profile
