A truck carrying freight ≠ a person driving home groceries. Groceries that typically fill up a car's trunk just for 2-3 people; a bicycle isn't carrying that. You'd need a rickshaw-like cart hooked onto it. They do exist though, for passengers, so making one for personal cargo loads is doable.
I wouldn't want to do any of that in winter, though. Snow, ice, and sub-zero wind-chill (plus the further cooling effect while moving) are not when anyone should ever be on a bicycle.
Also, driving to a larger grocery store is non-negotiable for us because they're the ones who stock the lower-demand allergy-safe foods. Guess how much a corn allergy sucks in America, on top of others. While most allergies and medical conditions are rarer than not, they are a huge problem.
Didn't get me started on commuting - and youn literally can't remote-work a labor job. Imagine having to make a 30+ minute car commute on a bicycle on top of a 9+ hour day.
So while yes, fuck cars, bicycles are not anywhere close to a magic bullet. Our entire civilization needs a comprehensive bottom-up overhaul that addresses every problem simultaneously, since most of them are interconnected.
