> an idle brain is useful for creative thinking and problem solving.
This is a more reasonable argument, and I agree. It is often useful to have quiet space to think. That said, I prefer to put the dishwasher on, and go for a walk outside for 15minutes, than to stay inside doing the dishes. The dishes themselves are not in and of themselves important. In the case of the streetlight, many people may be too busy navigating the streets to relax properly into a good idle state, or they may be pissed off and want some light-hearted fun; we should not make value judgments on them for that.
> it [is] important to unplug from technology on a regular basis
Whilst I might not necessarily disagree with you on this point, people often make this claim with no actual evidence or reasoning. Why is it important to unplug? In some situations, I can clearly see a benefit - for example, eating dinner with friends, pulling out a phone to check social media disrupts your ability to connect with your friends, makes you seem rude, and will likely reduce the quality of your interaction. When I'm on the train to work in the morning, listening to music and reading web articles on my phone seems like a net benefit.
There can be benefits to avoiding technology and to doing things properly and in-person - but those should be evaluated on an individual basis with logic, rather than with a general appeal to puritan work-ethics and ascetism.
