Well this is already possible with cash (and some countries more than others have flourishing grey and black market economies where business is conducted with it) So crypto only helps here if the service you're providing is over the internet, and not using an intermediary platform which is a legit business for payments, escrow, or service fulfillment tracking (so things like etsy, bandcamp, fiverr, and upwork are mostly out, though you sometimes can cut out the middleman on those platforms). There are a few services people will still arrange outside of a platform, I think online sex work is a big one (also because people don't want things linked to their credit cards) But it could also be useful in countries that are moving to ban cash
