I agree with your point that not every application needs this degree of separation of concerns. But the problem, in my experience, is that individual developers are not very good at knowing where that line is. And the line can move over time as the application grows.

For any project that I'm responsible for, I don't feel comfortable designing around a paradigm unless there are some guard rails to prevent developers on my team from accidentally tying the code in knots. How enjoyable is this for the developers? Are they sprouting angel wings and playing the lyre as they write code in iambic pentameter? Probably not, no. They have less freedom of motion than if they were left to their own devices.

This is a larger debate: where to fall on the spectrum between unadulterated developer bliss and having an application that is still maintainable in 5 years. I don't put much stock in developer bliss, but I do appreciate that the sword cuts both ways.

I’m curious if the statement “happy developers create better systems” holds any weight.
