What a thought provoking post. First thing to be sure of, when you're looking at Etsy in the current context, you need to be filtering by "Handmade" and in the UK to get an actual view on what makers are selling at what price. Most other items on Etsy are Chinese import, a real shame considering Etsy's roots.
I sell on Etsy, and I'm actively trying to build a business out of woodworking, or making in general. I suspect that's quite at odds with a portion of woodworking sellers, who just want to sell the things that they are inspired to make to make a little money to fund their hobby or maybe put towards a holiday.
"Selling things that you are inspired to make" in my opinion is categorically at odds with "selling a product that you make". I have put thousands of hours into developing products that I can make in a time frame that makes them profitable. It's a skill that I think most don't have.
Take for example the hand sanding blocks that I make...

It's a simple design, but it took me 3 months and hundreds of hours to refine the production process to ensure that I could make each one in under 10 minutes. (including laser cutting the velcro, engraving the logo, finishing, packaging etc). At £25 they are a premium product, but it's profitable even
selling them wholesale.
Making, and even product development are easy and fun compared to what is actually required to sell... marketing. Makers that are interested in marketing are already likely running successful businesses. The rest of us, are probably frustrated that "if you build it, they will come" is just not remotely true. Platforms like Etsy are "supposed" to solve this, by providing a steady stream of customers to our shop, but of course, they end up so big that now you need to market within Etsy. Lots of effort is needed.
