The cynic in me views this as yet another attempt at fethishizing nature by people who choose to live in sterile urban environments. The problem with this type of fetishization is that it eventually combines with class privilege to produce narrow public policy that seldom promotes the public good.
Furthermore, those that live in less-urbanized less-sterile locales are painfully aware that nature and her army of insects always has the upper hand.
Inherent in your statement is the idea that privileged people choose to live in urban environments, which is probably false half the time. I choose to live closer to work in an apartment to minimize my costs and travel time. I would love a backyard.
Europe is quite densely populated in some areas, and insect populations in these areas have dropped to a fraction of past numbers in some areas, over only a few decades. It's quite reasonable to try to do something about it, as we're actually dependent on insects, to a likely significant but somewhat unknown extent.
That there are insects in some places doesn't mean the issues with insect, and general biodiversity loss suddenly disappears.
Bugs are everywhere, but there are species disappearing every at a rate much much higher than they should disappear for natural reasons.
There certainly are cases where fetishization can be part of it environmental policy, but usually it's then about something you can brag about, not about the impact light has on the sex life of bugs.
Even with the possible fetishization of nature, most people still don't care enough to be willing to lower their standard of living, even quite superficially. Generally, I would say cynicism regarding environmental policy is often misplaced, as even terribly inefficient policy makes the existence of the larger issue apparent, and opens the door to better and more informed policy the next time around.
Look at almost any are of legislation, the first plodding steps into a new area is often hilariously misplaced, or terribly expressed with the 20/20 of hindsight. Regardless, they were necessary steps. In some areas, biodiversity arguably one of them, the first plodding steps are taken just now. It's progress, if small.
