I feel like you're being a bit disingenuous. The article stated that market competition has mostly thwarted the attempts of any single big tech company reaching the levels that WeChat has in China. If you're proposing Visa has done that (across all categories, not just financial), I'd be curious to hear your proposal.

To answer your question, though, Visa doesn't process payments for the dozen or so cannabis shops in my town and they are all thriving. I'm not saying it's common, or easy, but the answer is yes.

Well you've disproven my point. Good work.
