Points 2 and 3 are almost identical for every single business on Indie Hackers.

Subscription model. Internet delivery, with email and social media marketing.

After that, you're back to the square 1 of "now I need an idea". The post had some good points, but for the IH audience I'm not sure it would change much about how they analyse business ideas.

An Indie Hacker isn’t going to buy a pub, or start a VC fueled startup for that matter. OTOH under the umbrella of internet delivered ideas there is a lot of choice as what to work on! And the internet bit could be trivial with most of the legwork going on in real life, or it could be a pure internet play all online with a rich app.
