Sure, in isolation I would prefer a car staying in its car-lane to a bicycle driving all over the sidewalk. But then, this change doesn't have to happen in isolation. The Netherlands is a great example of a decades-long investment in pedestrian-first & cyclist-first infrastructure over cars. Cycles have their own dedicated lanes, increasingly not just painted on the car-lanes but separated from both the car lanes and sidewalks with elevations. And as they're ubiquitous and well-kept, cyclists have no real reason to drive on the sidewalk. Cycling on the sidewalk just isn't a problem of any significance anymore in most places in the Netherlands. But when I went to Berlin and cycled there, I often found myself on the sidewalk by way of convenience and safety. The solution isn't to say no to bikes and have cars instead because cars have dedicated infrastructure they stick to, the solution is dedicated infrastructure for bicycles and incentives + enforcement to make them stick to it. It works very well in the Netherlands, which was actually, at one time, a country with tons of development geared towards cars.
