Ask HN: Why getting paid on the Internet is still so difficult?

I wanted to start selling on the Internet by myself. On my website, not on eBay, Amazon or Upwork. I know only HTML and a little bit of JavaScript. I can use some script from StackOverflow to do the job for me. I can install Google Analytics script and setup a simple static website with a domain.

Is there any easy and fast way for me to get paid? By easy I mean doable with my skills (no backend coding etc). By fast I mean I can start charging in less than 2 hours.
