First of all, techy nerdy people like things to be easy too. They're just somewhat more likely than other people (on average) to overcome not-easiness.
Second of all, how long is IndieWeb supposed to cook for before it's supposed to be ready for a broader audience? This is no shade on the IW folks if they like what they're building. But if what they're building is supposed to catch on somewhat, what's the path supposed to be? The project seems to be 15 years old already: https://indieweb.org/IndieWebCamps#
Exactly I have limited time in my life to tinker with stuff.
If something is important for me I can waste hours setting it up and running.
If it is something new to me, if it doesn’t work out of the box I most likely will just move on.
