This is an interesting idea. I don't want to just scrape by though, I'd like to use the skills I've acquired over the years to do something that doesn't involve being a full time employee for a company.

Yes it depends heavily on your preferences. I’m attracted to this idea as Im feeling fatigued with programming, it can scale well without even inventing or coding anything, and perhaps narcistically I believe if you throw a excoder/math person at the analysis of markets and profitability you’d get a massive advantage over a typical seller.
