I’ve commuted to work by bicycle maybe 2 decades out of my career of almost 3 decades, NEVER with any bicyle worth more than 200 EUR (during my time in The Netherlands I always got second hand bicycles … well, more likely 4th or 5h hand) and you clearly have no fucking clue what you’re talking about.
You’re talking about, maybe, the consumer high-end “recreative” cycling, the kind that’s sold to fad-following consumers who will at most pull out the bicycle on a weekend day, put on a “Tour de France” disguise (complete with “sponsor” sticks) and go cycle to be seen cycling.
In countries were people actually cycle for utility purposes those are a tiny fraction of people and the “cycling industry” is something else altogether than what you describe. Normal people use normal bicycles which are not too expensive, especially because you really don’t want to park a 1000+ EUR on the street, not if you want to come back and still find all of it there.
Further, even at the high-end, the actual pros know how to fix their own bicycles and know the value of standardized components: it’s really only the “two-wheel fashionistas” that would go for overpriced bicycles with non-standard elements.
Going after cycling because of a few idiots (and there are idiots in every human endeavour) and calling it pro-Ecology is the pinnacle of stupidity and doing the work of the enemy.
