In the fiat world, online businesses in order to charge people money, they need to:

1. Register a company, deal with accounting stuff and the yearly maintenance, maybe even tax if they don't do their homework.

2. Use payment processes, most likely Stripe, which means need to pay again.

3. To use these payment processes also requires to have a bank account.

what a well-designed loop, layers of layers of middlemen sitting in between, but guess what you really need now? A simple site, spin up a node, and focus on your craft:)
