I think that I understand what you are saying, so let me repeat it back to
you in my own words.

I tend to agree... the only reason we aren't as "concerned" about non-IoT
things is because we can (in theory) update them, the devices are used
directly by humans who sometimes notice if they are broken (or p0wned),
and the passwords, as weak as they are, can in theory, be stored in the
human, rather than in the system. (In practice: it's better to let the
browser store them)

So, I see this as an opportunity...
It's like the book with no letter e:
https://en.wikipedia.org/wiki/Gadsby_(novel)
artists impose arbitrary restrictions on themselves in order to do better
work.
The IoT space is restrictive, and has no humans to pick options or store
passwords, so we have to do it correctly. It's also much more of a
greenfield with no clear incumbent. Therefore we can throw away many of the
things that turned out to be unworkable/insecure, like passwords.
