Some time ago, I read this article

"The War on Informality" https://www.asomo.co/p/the-war-on-informality

I was reminded of it because today I saw this video

"Walmart's Self-Checkouts Get WORSE, Paying Customer Ends Up in Prison"

In Bitcoin land we have "The Beef Initiative" and tons of others easily discoverable on https://www.lightningnetworkstores.com/?tags=food

Not only that, but if you do just a little research to find your local farmer (farmers markets for example) you can even participate in the informal fiat economy.

Quick shoutout to AGORA sub too, although I have my doubts about a thread based website being used for ecommerce.

Any aspiring entrepreneur should see the customer dissatisfaction out there with the formal economy and act to capitalize on it.
