What you've just said is a common refrain, if you haven't already seen it please take a look at these two videos that attempt to address part of what you're saying. I found them very interesting when I came across them years ago and it changed my view of what's possible or even good!
https://www.youtube.com/watch?v=xSGx3HSjKDo "Who else benefits from the Dutch cycling infrastructure" (old people, disabled people)
https://www.youtube.com/watch?v=Uhx-26GfCBU "Why Canadians Can't Bike in the Winter (but Finnish people can)" (frozen Finnish winters)
So Canadians bike less in winter than some Finns (not all, as the author of the video himself mentions that Oulu stands out among Finnish cities in this regard) yet those Finns make only 12% of winter trips by bike. That means the vast majority of winter trips they make (88%) are not by bike. In a small town, which is 12x6 miles judging by google maps yet has 590 miles of bike paths. If anything this proves cycling in winter is not an option for the vast majority of population.
And yes, the Dutch have their bike paths and bike without helmets, we all know that. The secret is the lack of elevation and living in crumped cities: on average a Dutch person bikes 3km per day [1].
