Is it easy to live without it? Can you go about your business without it?
I was in China in Sept 2019 (what good timing..) and without WeChat I did feel if people thought I was from some remote remote village. I saw an old lady who had a rickety old cart with coals and a big pot, inside the pot were warm corn she was selling, and on the cart was a QR code to pay her with WeChat/AliPay.
You can fill out official government documents in WeChat.
