I believe Nostr will enable way more self-employment and entrepreneurship.

Unscalable businesses, ones that require personal attention have a natural outlet here on Nostr. If you're using a platform to sell your services, you have to pay the platform and your work gets taxed. Building out via word of mouth, SEO and a website is a whole lot of work in of itself.

On Nostr, you can show endorsements. You have a natural network of people you know. There's an easy means of payment. And most importantly, you don't have to pay a tax to a platform. You can grow your own business without being dependent on some platform.
