Biking is not meant to replace everything. More people biking means more room for people that cannot bike. Bike-heavy cities like Amsterdam show that most of your "facts" are incorrect (bikes can be used to transport goods, are usable when it rains, are used by a large part of the population). That's a trope common when bike displaces cars, but studies show the reverse (for example in Madrid: https://www.sciencedirect.com/science/article/abs/pii/S02642...). Also, biking is good for health despite the risks (for example https://www.bmj.com/content/343/bmj.d4521).
