I don’t disagree that there are other forces aside from market forces.

In the case of people paying via WeChat though, it is legitimately market forces. If you don’t use WeChat, people around you will urge you to use it because it is so much easier than cash. No more going to the bank. No more handling change. You just open your phone, scan, and pay. Small businesses you frequent where you get to know the proprietor will tell you they think it’s a little funny you’re paying in cash and even offer to help you set up your WeChat Pay because it is “so easy.”

I honestly don’t know anyone other than me who pays for things in cash. Everybody else is on WeChat. Nobody forced them to; it was just rapid, collective adoption, analogous to what happened when smart phones hit the market. You can still buy dumb phones that work great, but nobody does.

As it so happens, I lived in China for 9 years, swam in the startup tech circles, and built a startup around WeChat. I can tell you with authority that you are wrong that WeChat won through market forces. China operates by allowing many startups to flourish, and when a particular industry becomes dangerous or important to their national interests, they shut down all but one, and put state backing into that one. They play king makers. Tencent, and WeChat, while well run and built, is basically state owned software.

I saw this whole ordeal play out with Twitter clones. There were maybe ten with traction. Then the gov stepped in and there were none. And then Weibo rose from the flames as the winner.

Speaking as a former weed delivery driver in California who got robbed at gun point twice... I honestly cannot wait for cashless to come. You know what's fun about dealing with cash? Nothing! It sucks! At least give me the option to opt out of having to deal with people who transact in cash and give me a badge that says "This guy doesn't carry money!" That seems fair to me since I don't want to be involved with that nonsense or the problems that come with it.
